When rebooting after ostree update hitting minimal bash

After updating and rebooting, grub seams not to show the boot entries and I end up with a Minimal BASH-like … message and grub> _

When I type in ls I get: (hd0) (hd0,msdos2) (hd0,msdos1)

If I do ls (hd0,msdos1)/ I get: lost+found/ loader.1/ ostree/ loader grub2/

What can I do to get to a working system, preferably without reinstalling everything and restoring from backups?

Are you on F31? If so, you probably ran into this issue.

As far as I know I am not, I should be on 30

So this is what finally got me to a boot menu leading to a familiar operating system:
grub> unset blsdir
grub> blscfg (this results in a error: …/…/grub-core/commands/test.c:436:false.)
grub> normal

so I checked and i am running:
ostree://fedora-workstation:fedora/30/x86_64/silverblue
Version: 30.20191004.0 (2019-10-04T20:48:31Z)

that’s 30 right?
