Crash when starting a VM with its window still open after it has shut down

[conath]

UTM crashed when I had just shut down a VM using the power button in the toolbar. Then I clicked the play button it crashed. The same happened twice, once with the large play button and once with the one in the toolbar.

This VM config is special because it uses custom EFI and EFI Vars images to retain a 1280x720 resolution across reboots. This might be a factor here because the crash seems to be related to the VM window resizing.

Configuration

• UTM Version: 2.1.2 (31)
• OS Version: 11.3.1 (20E241)
• Intel or Apple Silicon? Intel

[muratdk23]

Issue still there in 2.1.2 version.

[osy]

@muratdk23 can you get a new crash log? I don’t see it on my side anymore.

[muratdk23]

debug.log

[osy]

Sorry I mean crash log from Console when it crashes. (You can look at the template when creating a new issue if you need directions.)

[muratdk23]

I meant when I shutdown windows 10 on arm and try start again it trying to boot but shows BSOD.

[osy]

Then it’s not the same issue.
