The disk is after that in read only !

Every now and then device mapper kicked in and caused trouble: dup to 20210708 results in unwanted device mapper - #5 by marel

I can be wrong but this looks like a hardware problem to me, it does not seems to me like linked to a particular update.

Can you check the journal to see if there are any any smartd messages for the disks you have? You can also run “smartctl -a” but I find that output hard to interpret.

To check btrfs you might check something like “sudo btrfs check --force -p /dev/sda2”
