    On Windows 11 in Unity 2021.3.9, there is a bug that causes unity to run out of Windows User objects.
    Once that happens the console in Unity prints this message:
    The current process has used all of its system allowance of handles for Window Manager objects

    After a while windows breaks and starts to spawn a lot of windows on screen, and Unity freezes:
    This a severe bug that happens only on windows 11 and pretty much makes it impossible to use Unity

    Steps to reproduce:
    - Start unity 2019.3.9f on windows 11
    - Just use it for a few minutes, import packages, enter play mode and it will break

    Hi, I'm watching this as I've got something happening almost identical to this. However all I manage to get done is create three squares in a new project. Bam 10,000 user handles. :confused:

    Also happens in 2022.2b7 and b8... :(

    Sometimes it even green screens if you leave it on that message without closing pretty quickly.

    I don't know if this is a Unity bug or a Windows 11 bug (that also updated recently). It only seems to happen when running Unity though.

    I'm having the same experience with 2021.3.9f1. I have been experiencing the handles issue for over a week now and since yesterday this specific issue with all my Windows processes opening up in the background. Stumped!

    Hi, are you on insider version of Windows? If so, this is a known issue and we have reports that it has been fixed in Windows build 25201. It would be great if you could confirm whether it fixes it for you too.
