Context: I updated my CachyOS (Arch) BTRFS system. Some new things caused few problems especially brave browser(missing tabs), some icons missing.
So I wanted to go back to previous snapshot.
What I did: I first restored my home subvol which I saved before update. I worked.
Then I tried to restored my root partition. This is where I got the problem.
I got this error.
I would really appreciate URGENT help
If you need any more details I can provide.
Start by following the instructions on the screen in order to get an error log.
If the root account is locked, which cachyos does by default, then you won't get anything from this screen.
I had to fix by usb booting and troubleshooting (a different issue though, I was playing with initramfs generation).
