    Since 2021 we experience crashes produced by our tools. They worked fine in earlier Unity Versions
    We are currently working on 2021.2.4f1

    The "EditorWindow.HasOpenInstances" produces the crash if the user enters/exits the playmode.
    The bug occurs very inconsistently and can't be easily reproduced.
    We had multiple scripts hooking up in EditorApplication.update and calling the underlying "Resources.FindObjectsOfTypeAll" all of them produced atleast one crash.

    Our crash stacktrace looks like this:

    The code referenced:

    1.  
    2. static BuildMachineTest()
    3. {
    4.      EditorApplication.update -= OnUpdate;
    5.      EditorApplication.update += OnUpdate;
    6. }
    7.  
    8. private static void OnUpdate()
    9. {
    10.      if (EditorWindow.HasOpenInstances<BuildPlayerWindow>()){...}
    11. }

    Is this a known issue? Am i using the editor callbacks wrong?

    Thanks for your help!

    Same here !
    We have multiple tools on our build machines, all of them worked in 2020.3.10 and now that we are in 2021.3.13 crashes occur systematically. So far we observed this :
    - Crashes happen between 30 min and +4 hours
    - It happens on different tools
    - For a given tool the stack traces vary (Native Crash Stack Trace)
    - It happens on different computers
    - Processed assets vary
    - Enabling 'AssetPipeline Parallel Import' doesn't change anything.
    - Also happen in 2021.3.14 (with more issues related to the AssetDatabase)
