Reset mime.type ? foliate not working after Fedora36 upgrade

Since I’ve upgraded to Fedora36, foliate won’t open .epub files anymore. The issue is documented upstream at glib2 2.72.0 causes "Empty response" · Issue #878 · johnfactotum/foliate · GitHub.
Solution involves resetting ~/.local/share/mime/mime.cache , is there a command line tool for that? Is there a way to reset and do a diff to see what changed?
Shall I raise a Bugzilla issue for fedora ?

remove the file and then`update-mime-database ~/.local/share/mime.

It looks like isn’t always fixing the issue,

I’m not sure about generating a diff since it is a binary file.
