Plasma Vault has been bumped to 6.3.90 in Rawhide, but this doesn't work at all, because it requires gocryptfs, and we don't have that packaged in Fedora. You cannot create any vaults. The software is not usable. We either need to package gocryptfs and add a dep to plasma-vault, or downgrade plasma-vault back to the previous version.
...or, as Nate suggested, "patch out the change to only allow gocryptfs for new vaults I guess, which was https://invent.kde.org/plasma/plasma-vault/-/commit/ba292cce35907707cab41e651fd86b847117ed73 "
I'll try to revive https://bugzilla.redhat.com/show_bug.cgi?id=2241620 as that's the better option.
