Add Library window is blank

[lordcirth]

Settings > Storage > Add Drive. The window is blank as shown. The New Folder and Select buttons do nothing. Cancel works.

Adding my Steam library paths via flatpak didn't help. Neither did -vgui. I tried Big Picture mode (-tenfoot) but apparently it just doesn't have the Add Drive button.

NixOS 24.05 (Uakari); steam installed via nixpkgs doesn't have this problem.

Had exact same problem, re-check that you are adding paths via flatseal in "other files". In my case /mnt/Games/SteamLibrary
