I guess I borked my System (lemmy.today)

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.

1001090084

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+d and got 👇🏽

I typed my password and went into maintenance. Typed journalctl -xb and got 2667 lines 😵‍💫. While scrolling mindlessly, this looked like something 👇🏽

This is my refind_linux.conf 👇🏽

Did you try regenerating the initramfs after rolling back the root partition? That's what's wrong whenever my install is fucked. I'm unfamiliar with the recovery console but see if you can

manually unencrypt cryptsetup open /dev/nvme0n1p2 root,
mount mount /dev/mapper/root /mnt -o subvol=@root mount /dev/nvme0n1p1 /mnt/boot,
chroot into the system arch-chroot /mnt
and run mkinitcpio -P

Edit: Oh the screenshot just loaded in. The problem seems to be that you can't mount /boot? What happens when you try to mount it manually?
