I’ve had that rarely, and usually because the sim fell over for some reason, which again is rare for me. I’ve never seen that in 2024, but I did see it a few times in 2020. When the sim fell over it would fail to delete a file that it used to detect an unsafe shudown.
The file I was thinking of is called “running.lock”, and is in the “LocalState” folder, adjacent to “LocalCache”.
I assume that is possible in 2024, so I wonder if that file is left there for some reason, and is not being deleted on a successful shutdown.
I found an old post of mine about this:
Are there any files in that location in 2024 that look similar to “running.lock”?
