Native debugging
I've been getting an annoying issue on my project where the game suddenly permanently freezes. It occurs at random times and I haven't been able to find the specific part of code that is causing it. It's a spaceship game and by heavily increasing the number of spaceships spawned, I find that the freeze occurs a lot quicker. Usually it happens randomly (like after a few minutes of letting the game run) but when there's lots of spaceships it happens after 5-10 seconds of running the game.
The freeze occurs both when running in Unity editor with or without profiler and when "Build and Run"-ing.
I've already gone through my code base to look for possible while-loops that could be getting stuck etc. Usually those are easily found by pausing VisualStudio when attached to Unity, but in this case I end up with "No compatible code found", indicating that we're getting stuck somewhere in Unity's native code.
I've been trying to follow the steps in this thread https://forum.unity.com/threads/usererror-how-to-find-your-infinite-loop.378384/ but after attaching to the Unity.exe process and pausing execution, I am getting stuff like "object.c not found" / "mini-runtime.c not found" etc.
And Watching on "mono.dll!mono_pmip((void*)0x0d51f480);" gives "Module mono.dll not found."
Can anyone help me on debugging the issue?
EDIT: After some searching, I've found that the files VS was asking for are in the installation location of Unity, in my case C:\Program Files\Unity\Editor\Data\ So that's a step ahead.
Now I've got the following stacktrace:

My game relies heavily on Coroutines and I've heard that Unity's Coroutines are quite fragile. Could it be that my freeze issue is due to my usage of Coroutines to control flow? And that would explain why it occurs more when there are a lot more spaceships in the scene, as that would mean a lot more coroutines happening. Any advice?Unity.exe!Random_Get_Custom_PropValue(void) Unknown
