I'm running Bazzite, which is immutable, so the root filesystem is read-only, but I've been having an issue pop occasionally where the rest of my filesystem, including my home folder, becomes non-writable. I can't do much, and constantly get popups about folders being non-writable until I reboot, and then everything goes back to normal.

Does anyone know what can cause this to happen? And is there a way to deal with this without rebooting when it does happen? I don't know when I'll be able to try anything out since it's not a frequent issue, but it has happened to me several times in the past.
