Event loop? Suddenly can't start any programs on riscv64

[oskar-skog]

While testing #26493 on #26491, Shell stopped responding to any input so I closed the terminal window.
(IIRC: Shell died from SIGINT but the terminal window didn't close itself, probably because the child process was still running.)
Probably not related as I've ran into it before, but it's the last thing I did before I ran into this new issue.

I can't start Terminal, I can't start any program that runs in terminal.
I can't start File manager, TextEditor, or SystemMonitor.
"Run..." doesn't even open a dialog.
"Exit" opens the dialog, but I can't power off, reboot, or log out.

When I click on any of these, I see a bit of CPU activity and then nothing.

No errors are seen on the console, but it looks like the event loop has ceased working.

I have since reset the machine, so I won't be able to do any further testing unless I find a way to consistently reproduce this issue.

I used DisplaySettings as well, but I don't remember when I closed that window. I'll test it again later.
