Flatpaks can't seem to access most folders, including /home

Hi, did you solve your problem?

It seems I have the same issue out of a sudden, when my app (GNOME Backups) was working just a day before (thread: Gnome Backups (DejaDup) suddenly unable to open paths!?).

Albeit I changed something, but I don’t think I could’ve changed anything so drastically so that GNOME Backups won’t be able to access any directories I want it to access.
