Game crashes when deleting an animated character in a mobile VR game, no errors

I’m working on an Android game (specifically, a mobile VR game) and I’m having these completely random crashes sometimes during gameplay when deleting animated characters. For reference, it’s a multiplayer game, and the animated characters “ragdoll” when killed by players but if they escape then they’re deleted. It seems that when they’re ragdolled then destroyed there’s no issue, but if I destroy them while they’re animated still then the crashes happen. There are no errors being thrown beforehand, and unfortunately the stacktraces I’ve gotten are all over the place from these crashes, but they seem to consistently referencing the internal animator functions

Here are a couple examples of the stacktraces :

Also it’s just in the build. It never crashes in editor, even left running for hours.

bump. I really can’t make heads or tails of these stack traces, they don’t point me in any particular direction beyond being related to the Animator and I can’t exactly get rid of it.

My most recent crash has been at
CleanupScaleConstraintAnimationBindingInterface
if that helps narrow it down at all, but truthfully the stacktraces have been all over the place
