Could the game crash be a GC problem?

  My release version of the game was stuck at the end of the run, but the game didn't crash, just like the infinite loop. I used the following method to see what was the cause:

1: use debug version of the release, Attach vs to release version-> to suspend all threads, to see the main thread of the call stack, but the main line running place has reached the ntdll.. No user code.

2：use the task manager Dump, use Windebug to see the call stack, stack information is as follows: I guess there is no space can be allocated, but then there is a lot of computer memory.

3: according to this link: https://blogs.unity3d.com/cn/2016/05/24/breakout-how-to-stop-an-infinite-loop-in-a-unity-c-script/, but my CPU occupancy rate is 0, as the code has not run.

  What should I do to debug or find the cause of the problem? I hope someone can help me, thank you very much.
