iOS Crash Log Help. Build crashes at random points, can't replicate in the editor

I am getting random crashes in my game. The crash logs are almost always the same, but I can't replicate it in the editor. I have attached a picture of a crash log from xcode, if anyone has any idea let me know. It crashes on android builds too but both are very rare. I understand everything until thread 6, about after that I'm not sure where it's coming from.

If anyone has any ideas let me know.

Thanks!
