FWIW I had the same issue under Fedora 40 Bazzite. For a bit I was having to shut down to avoid the problem you describe, and then they changed something else and I couldn't even shut down cleanly from within the DE. Things have been sooo much better since the upgrade to 41.
Way back when it was SkyDrive, for some reason I was given some huge (for the time) amount of space "for life". Can't remember why. For being a Windows dev maybe? Idk.
Some years later, I did an Office sub for a couple years, which also came with OneDrive space. When I let the Office sub expire, the fuckers took away my lifetime space. Cunts.
Oh huh. Is that a QEMU option? I'm new to all this.
