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.
EDIT
- I used BTRFS Assistant to restore the root partition. And I did it while the OS is running.
( I previously did that and got no issues )
- I pressed
crtl+dand got ๐๐ฝ
- I typed my password and went into maintenance. Typed

This.
The gist of how to fix it goes like this: Boot from USB, mount the root filesystem manually, and check the contents of /etc/fstab (on the mounted root, not the one on the USB drive). Check what it's trying to mount as /, and update to correct values if necessary.
UUID remains unchanged. And matches with both fstab and refind_linux.conf
