    Are you able to share a crash dump from this crash?

    Can you put it in a zip file and then upload to some kind of file share service like google drive?

    Yup!

    It seems the crash happens because your code calls Thread.Abort() inside a C# finalizer. Here's the reconstructed callstack:

    Code (csharp):
    1. 000001e06be61c9d() // Thread.Abort_Internal
    2. 000001e06be61bd3() // Thread.Abort
    3. 000001e068d0f34b() // NetworkLib.NetworkManager.Close
    4. 000001e068d0f023() // NetworkLib.NetworkManager.Clear
    5. 000001e0ce9d54e3() // NetworkLib.NetworkManager.Finalize
    6. 000001df960a183c() // System.Object.runtime_invoke_virtual_void__this__
    This is probably a bug in Unity, as we shouldn't crash like that (if you report a bug, we might fix it). However, calling Thread.Abort() in general is a pretty bad idea. I would use different interrupt mechanisms like System.Threading.ManualResetEvent instead.

    Thank u very much. My unity version is updated from 2020.3 to 2021.3. My project is worked well in 2020.3, so i have the question. I will check my code and thank you once again.

    Hi, master. It seems difficult to analyse with minidump. Rencnetly i try to use Windbg and Visual Studio to analyse, but not find a way to map addresss to method name. I have read Manual of WindowsDebugging, and tried mono_pmip command in visual studio, but it doesn't work with minidump. So how do you map addresss to method name. I'm looking forward to your reply.

    There is no straightforward/easy way to do it. The way I do it is locate a MonoDomain pointer somewhere on the stack, then look at jit_info_table field. It contains all managed functions in it and it is sorted, so you can do a "binary search" manually. It is tedious but at least allows figuring out what went wrong when everything else fails.
