(SexLab SE) Facial Animation CTD

[Imperfected]

This is a persistent and oddly specific problem I've been working through, where starting a SexLab animation with either the "Expressions" or "Lip Synch" animation options active causes a hard CTD.  However, this is only the case when using a female character; using a male character, even in SexLab scenes with female characters, does not trigger the CTD.  Disabling the options allows scenes to progress normally, though I believe it may be the cause of problems with mod-added animations (from ZaZ/Defeat, such as the post-rape trauma poses) as well.

 

A few notes:

 

FNIS builds clean.

I have tried it with minimal animations installed and SLAL SE packed with animations, with no difference.

I have tried completely reinstalling SexLab and XMPSE, along with all of their dependencies.  Nothing is overwriting XMPSE.

I have run LOOT and manually modified the load order to make sure XMPSE is loading last.

I have also tried disabling all mods, and doing rolling re-enables to determine where the problem is.  As above, with a male player character I can install up to the full complement without issues; with a female player character even SexLab by itself with dependencies (and XMPSE with dependencies) is problematic.

I have tried running both with Racemenu SE Alpha and with ECE (sans Racemenu), with no difference.

I have tried installing the MFG Fix for SE to see if it would fix it, with no difference.

I have tried installing the SKSE64 Engine Fixes, with no difference.

 

The only lines of interest in the log file:

[06/29/2018 - 07:42:16PM] error: Native static function ForEachMorphedReference could find no matching static function on linked type NiOverride. Function will not be bound.
[06/29/2018 - 07:42:16PM] error: Native static function GetMorphedReferences could find no matching static function on linked type NiOverride. Function will not be bound.

...  every other error line is related to optional dependencies (ie, not running DAYMOYL with Defeat, or Open Cities with Live Another Life, etc.) and unrelated to SexLab or animation.  I tried a few different variations of Racemenu SE Alpha and standalone NiOverride, and it doesn't seem to make a difference in whether or not these errors appear.

 

What I'm gathering is some people have these functions running fine, and I'm wondering if possibly there's a "hidden dependency"--something like PCEA2 or the like--that's adding functions or skeleton data that's missing, but really at this point I'm just taking blind guesses.  If anyone's running the latest versions (of SexLab, SKSE64, and XMPSE) with facial animation working on female PCs, and wants to share their animation/skeleton related mods to narrow down my search, I'd appreciate it.

A note for anyone who's having problems:

I wouldn't say I've "fixed" it, but I've at least tracked down the CTD issue to not having a good MouthPartF.nif, which might be an issue you run into as well if you're trying to use purely Skyrim SE mods for your skeleton and body textures.  I found one in Oldrim Fair Skin Textures and updated it for SE using NifOptimizer, and that at least prevented persistent crashing, even if expressions are still a bit naff.
