Dear all,
I am running openSUSE Tumbleweed on my Laptop and yesterday my storage ran out, I think because some issue with snapper snapshots and btrfs. I tried to clean up snapshots I didn’t need anymore by creating a new default snapshot using snapper rollback and delete other snapshots. Then I tried to reboot and now my system is stuck with the message “”. This never finishes, even if I give it a lot of time.
Here the complete things that is shown (has some errors because of OCR):

I already tried to find out what the exact issue is by using GRUB edit and rd.break=pre-mount to get into a shell and then running btrfs check --readonly /dev/mapper/system-root and got a lot of error messages, which I wrote to a file which is 305 MB (!). These are the kind of messages it contains:

(and here, and it ends with)
ERROR: errors found in fs roots
I already tried running btrfs check --readonly /dev/mapper/system-root but had no success doing so.
I also tried most of what is mentioned here: https://en.opensuse.org/SDB:BTRFS until btrfs restore /dev/sda1 /mnt/usbdrive. For that I started from an installation medium into rescue, because I wasn’t able to mount my exfat disk in the other shell. This worked, but now there is no /dev/mapper/system-root anymore and I am out of my depth. How to I unlock my disk so I can then try the other btrfs commands from the guide?
Thank you already and if you have any other tips, they are extremely welcome!
