I've noticed that I cannot load my saved game and it will CTD at the loading screen and that happened to me after installing alpha 6 plugins release and making my character in racemenu using these plugins... But when I delete the plugins (skee.dll hudextension.dll) the game will load normally.

Same issue here. Every time I try to load a save with this installed, it'll go to the load screen and then CTD, but it works fine without this mod installed. This is only the most recent update to SKSE and Racemenu Alpha 6. Not sure if it helps, but I've attached my load order below.

I can't afford to lose Racemenu now especially after I made dual sheath redux works perfectly with it... I'm still investigating this issue and I think I'm kinda close to figuring it out... I'm thinking its something to do with other hud mods that conflicting with Racemenu plugins like a matter of time, iHud and SkyHud etc... I'm gonna uninstall them all and try a new game then saving and loading again after few mins of gameplay to see if it's gonna CTD or not.

I'm posting my MO2 modlist here. Maybe you can look through it and see what mods we have in common in order to identify the conflict. Right off the bat, I can tell you that I am using iHud but not SkyHud or AMoT. I'm not using DSR either, FYI.

Its the new version of XPMSSE (4.3/4.31) causing skee to crash, probably because of some untested/unimplemented skee function.

Just tested and can confirm, removing the latest XPMSSE but keeping Racemenu works, or vice versa, but having both on crashes when loading a save. So aers is correct.

You are right!... I've tried that also and it was fine... What a waste!... I hope it will get updated soon.

Might actually not be an SKEE sided issue. The patch notes of 4.3 say something about
'- esp without RaceMenu components added'
so maybe you have the wrong esp installed? Or something else from the XPMSSE esp breaks the mod?

EDIT: seems like XPMSSE now has scripts for MCM and RaceMenu bundled (if you choose the Racemenu option). So probably that's what breaks stuff compared to v4.20

EDIT 2:
some google fu - this seems to be a known issue, so there is a tutorial on reddit.
https://www.reddit.com/r/skyrimmods/comments/8d84nx/how_to_get_the_new_xpmsse_to_work/
Maybe try following that. Seems like you have to install oldrim NIO and delete the dll, and also do some script unpacking from a bsa.

Even with that it seems like some people have problems, and I'm sorry if you already did that. Just thought it was worth mentioning.

Nah there's definitely a crash on save game load. I tracked down the crash in skee and reported it to expired in discord; he'll fix it when he has the free time.

Thanks aers.

Is there another mod that uses Skee64.dll other than XPMSSE ver4.31?... I want to see if the save game gonna crash again or not.

Will simply reverting to v4.20 of xpmsse fix the issue, at least until it's fixed?
Edit: I reverted to v4.20 and immediately all saves loaded, race menu started functioning properly(there were empty menus), started a new game creating a character with an oldrim preset, and played for 21/2 hrs non stop with no issues(game ran better than ever lol)

@DragonJoe did for me.

How I fixed the CTDs on loading a save with XPMSSE v4.31 and RaceMenu Alpha 6.

While installing the latest version of XPMSSE, during the FOMOD installation, select the following options:

1. a. Character Creation: MCM.
   b. Weapon Style Randomizer for NPCs: None.
2. Done.

I appear to be getting CTD with alpha 6 aswell,going back to XPMSSE v4.20 does not appear to work for me. and trying what CycloneGamer mentioned did not appear to do anything either. I guess i'm doing something wrong?

I have some weird crashes after CycloneGamer's fix still... After I boot up my computer next morning after saving, my saves won't load up to game, even though they did the previous day. I can always load the save without SKSE, but not with it. I can still play a new game with SKSE though. Very strange. Not sure if it's SKEE related though. Mind you, I can play the game without the dll file from SKEE.

To be honest... I ended up asking 3 of my relatives with Ph.D. on computer science to assign their team to remake this dll build from scratch for me since it is an essential skse64 plugin for me now in Skyrim SE as it is in oldrim Skyrim before... You either delete this plugin for now and wait for the slow update process since they are doing it for free or asking someone you know in real life with knowledge outside of this community unless you want to deal with showy amateur responds.

I'm not sure what is causing it but the game crashes on every character for Racemenu when loading, quick, auto and even normal saves cause a CTD.

In my case, the peoblem is skee alpha 6. I tried to disable all of my mods and the game CTD when loading a save game. Then I tried to delete skee plugins and the game run fine.
I tried to use skee alpha 5 and it also CTD. Alpha 4 is working fine for me. My game version is 1.5.39 and SKSE warns me about compatibility issue, but it works.

I've been able to use the latest skee alpha 6 with the previous version of XPMS 4.2 with great success. All latest features work. You just don't get the styles included with the latest XPMSE. You also don't have the options related to choosing ECE, Racemenu or Dealy Mutilation. However, all of these mods still work with the XPMSE 4.2 skeleton.

I am trying to find the latest issue of Racemenu to install into my SE game. I have the latest SKYUI in, but this Alpha 6 leads me to Oldrim Nexus. I though Oldrim RaceMenu wouldn't work in SE?

Those of you attempting to make this functional in SE should also resave both racemenu esp's in the SE creation kit, as the oldrim page plugins are using old form 43. While not necessarily a contributing factor to this particular issue as it seems to be SKEE-related, it's still a good idea as using old-form plugins can lead to save corruption.

SOLVED!

Just updated XPMSSE to 4.32 so now i can use both RaceMenu and XPMSSE !!!!!

@TheDabKing, What did you do to get them to work?

@capella07 I updated XPMSSE to 4.32

@capella07 I was on 4.31 and had CTD (Crash To Desktop). I only upgraded to 4.32 with NMM (Nexus Mod Manager) and that's all.

My crashes also still continued even after I tried 4.32. I'm simply sticking with 4.20 until the next Racemenu update comes out and until the Styles functionality for the skeleton is considered stable.

Or you can all just install SSE Engine Fixes
until expired get around to fixing it
(it fixes all Load CTD issues, And I'm running Alpha6 + Racemenu + XPMSSE 4.32)

The crashes are due in part to the buggy alpha of SSE, So it's been recommended to install SSE Engine Fixes across many forums, this does indeed solve the issue with racemenu (in fact it even mentions this on the nexus page), EDIT: Fixes load CTD for ECE as well XPMSSE v4.3.2 - ECE

I use SSE Engine Fixes with Racemenu Alpha 6 and that fixed the loading CTDs but I would still crash after a few minutes of playing whenever I had XPMSSE v4.31 or v4.32, that went away when I reverted back to 4.20. So, in my case, I'm very content with 4.20 right now until Racemenu itself gets properly updated.

@PsychoWookiee that's a different bug then what the OP put, this issue is only for 'load game CTD'

It's pretty sure that this plugin will definitely causes CTD when you're trying to load a save game. And the price to solve this problem is unsure as just unload it or using the fix patch existed on Nexus ---- which may cause other problems (watch the BUGs report area you will see ).
My current XPMSEE version is 4.32 and I use ECE.
Waiting for update.

As has previously said, SSE Engines fixes resolves this issue. I am using alaph 6 with racemenu and the latest xm32 msse skeleton. I have no crashes on loading save games.
