Any way to restore or fast reinstall an installed flatpak?

[Alexander Larsson]

This is tricky, especially if you edited a shared file. For example
say you have both the freedesktop.org and a gnome runtime installed.
The later is based on the former, so it contains all its files. You'll
have two different checkout for these two plus a repo, and any shared
file will be hardlinked in all of these. If you modify the file itself
you run into two issues:

1) ostree assumes that all files in the repo are valid (i.e. they are
named by the sha256 of the content and the content doesn't match that
if it changed without renaming it). So, ostree will never re-download
such a file.
2) If the invalid file is shared, then even uninstalling one of the
runtimes will not get rid of the invalid object.

Maybe you can try ostree fsck --repo=$HOME/.local/share/flatpak/repo --delete
