I am struggling with a problem in Unity3D Android game. It is very hard to repeat Crash. It happens sometimes after 1 hour, sometimes 2 hours of playing every time in different situations and I can't find any reason.
I have tried different versions of Unity:
Also Mono and il2cpp compiler.
Can anyone give me at least a hint how to find the cause?
