Big Sur Installation Stuck at Login

After downloading Big Sur, my 2018 MacBook got stuck at (what looked like) 95% completion. A day later, nothing changed so I decided to reboot. Everything seemed to be going well until I attempted to log in. For some reason, I can’t make it past the login screen. A progress bar will appear below my user name only to get stuck at about 65% completion.

I’ve tried every kind of reboot, reinstalling Big Sur in recovery, first aid on all my disks, and reinstalling again after repairing disks. Nothing seems to work.

Is anyone else having this exact issue?
Experiencing exactly same issue with Macbook Pro 2018 (from OS 10.15). It is really frustrating
I can’t even restart, gets stuck at 10% and goes back to reboot again and again. What should I do next?
