Cannot use disks after reboot, gives error

Brief description of the problem

After a restart of my system, I’m not able anymore to access my drives or do anything with them.
Could someone help me?

what’s the output of “btrfs fi show” using the SSH access (if you have it)?
This reboot was not done after a failed disk replacement or anything like that, correct?

Can you also add a screenshot for the disks page?

Maybe it’s similar to the issue that was reported here, even though it’s a slightly older thread:
