Is this an error, or should I continue?

  1. 2 days back I ran garuda-update. on rebooting it got stuck on Loading initial ramdisk.
  2. Removing the nvidia drivers and some nvidia packages seemed to have fixed it.
  3. I took a timeshift snapshot (I know, I know, I should have switched to snapper)
  4. I reinstalled the nvidia drivers with mhwd, ran garuda-update and rebooted. It gave the same boot error.
  5. I needed to use my PC urgently, so I booted into the snapshot and kept using. It prompted me to restore the snapshot, which I dind’t do for sometime. (Was this a mistake?)
  6. Today I restored the snapshot and rebooted. It gave me the out of range pointer error.
