Fresh install, grub "Minimal BASH-like..."

I've just installed Ubuntu 20.04.4 LTS on my Thinkpad L14 Gen 1 AMD (no dual-boot). Both Secure boot and CSM are off in the Bios settings. After installation, when I try to boot, I get to a grub screen saying "Minimal BASH-like editing is supported".

I've tried following the most common guides to fix this problem. Tried re-installing multiple times as well.

The following commands get me to the OS itself:

set root=(hd0,gpt2)
configfile (hd0,gpt2)/boot/grub/grub.cfg

and

set root=(hd0,gpt2)
set prefix=(hd0,gpt2)/boot/grub
insmod normal
normal

After running the second set of commands and running sudo grub-install \dev\nvme0np1 followed by sudo update-grub did not fix the problem (after rebooting).

Runnig ls inside the grub screen returns me this:

(proc) (hd0) (hd0,gpt2) (hd0,gpt1)

Is there anything I'm missing on how to fix my grub?

UPDATE: Ubuntu 18.04.6 boots with no problems after installation.
