Fedora Silverblue/rpm-ostree not updating anymore "Bootloader write config: grub2-mkconfig" error in ostree-finalize-staged.service

I have several old Fedora Silverblue version:

rpm-ostree status -v
State: idle
Warning: failed to finalize previous deployment
         error: Bootloader write config: grub2-mkconfig: Der Kindprozess wurde mit Status 1 beendet
         check `journalctl -b -1 -u ostree-finalize-staged.service`
AutomaticUpdates: stage; rpm-ostreed-automatic.timer: no runs since boot

● fedora:fedora/36/x86_64/silverblue (index: 0)
                  Version: 36.20220818.0 (2022-08-18T01:32:08Z)

So the last update that was applies is stated there.
There is a big chunk of AvailableUpdate that may even be staged already, or not?

I missed that as GNOME Software does not show an error in case of a problematic update. It just silently continues. (It also prompted me for rebooting)

The command it suggests does not show a lot:

journalctl -b -1 -u ostree-finalize-staged.service --no-hostname

Looking again as this mentions grub, this is what is part of the update that is supposedly supposed to be applied:

                 grub2-common 1:2.06-47.fc36 -> 1:2.06-53.fc36

Arg I thought I have unpinned that old v35 Fedora already. But even if that should not be a problem I mean…

Trying again via CLI

This time CLI, not GNOME Software, ita gain claims it is applied correctly:
