Instant Shutdown when ShutdownMenu opens

To understand what is going on the first thing would be for you to reboot, turn on debug logging, then press the button that causes the issue. After turning the machine back on upload logs and post the url to the logs in this thread.

This sounds like another thread that I managed to reproduce and find a fix that worked for me but apparently not for the OP…

The button can be disabled if that is what you want…
