Strange crash with useless stack trace (PlayableController::PrepareFrame)

My game is working fine in the editor, never had any crashes or error reports.
But when playing a build (windows) I get sudden crashes, with seemingly no logical origin. The only thing I can think of is that it has to do something with the animator.

EDIT: turns out I get the crash in the editor as well.

I use the animator as a behaviour-tree and it has quite a lot of statebehaviours on it.

Spoiler: long piece of code

Crash!!!

========== END OF STACKTRACE ===========

**** Crash! ****

I think the only semi useful part is this;

But I get different stack traces sometimes, they all come from the directormanager however, whatever that is.

I doubt anyone can help me, but I have no clue where to even start, so it's worth a shot I guess.

 

I have the same problem.

 

Not saying I can actually help, but when did this start happening?
Since you're using Win10 (based on ntdll version), this might be related to a particular update that was recently installed or some drivers update.

If you feel confident, you could try collecting a user-mode dump (see MSDN here) and checking it with WinDbg/CDB. This could potentially reveal the real cause.
Note: it's good to do a system restore point before enabling user-mode dumps and disabling dump collections after you gathered what you need.
