Describe the issue
Using the UTM 4.3.2 beta release, I installed a Windows 11 guest from the VHDX for build 25346. I then tried to use Windows Update to get the latest Canary build (first I needed to update the two WindowsSelfHost registry keys described here). During the install process, UTM crashed.

I tried it three times, and UTM crashed at three different points during the installation (20%, 28%, 38%) so more likely this is related to overall load than anything specific that the guest is doing.

On the third attempt, I had left it running overnight, and woke up to find UTM still running, but the install progress only showing 38% (normally it should complete in well under an hour). Then as soon as I tried to move the mouse cursor into the VM window, UTM immediately crashed. I think the symptom was similar on the first two tries but I'm not completely sure about that.

The logs below are from that third attempt. I also have crash logs from the first two attempts, which I can add if they would be helpful, but I don't have debug logs for them.

Configuration

• UTM Version: 4.3.2 (84)
