Problem Grub Ubuntu

I have Ubuntu 22.04 Desktop installed on an NVMe drive with an ext4 file system. This is the only OS I have installed, however, when I try to load it, it jumps me directly to the minimal bash-like line editing is supported screen.

Looking for my drive where I have the /boot partition, I found that I have it on hd5, msdos3.

I then do:

grub> set root=(hd5,3)grub> set prefix=(hd5,3)/boot/grubgrub> insmod normalgrub> normal

Then I get the error:

invalid environment block error

Then an Ubuntu interface that says Checking file system loads and the screen turns black.

Can anyone give me an idea where to go? Thank you all for your patience.
