However, it might be trickier for GNOME users (as opposed to Xfce users), since GNOME system’s might require xdg-desktop-portal-gnome as a hard dependency?
For my Xfce system, I don’t have (nor need) any such xdg-desktop-portal-* packages.
If removing the package is not feasible, you can try veteran-linux-usr’s@novice-linux-usr’s temporary workaround of clicking the filename field and then pressing Enter.
