How to fix GRUB? Could someone interpret the bootinfo script results for me?

Good afternoon!

I have Ubuntu 22.04 running on a SSD. Everything was working perfectly until a few days ago, when I was prompted to install updates. Now, whenever I start my computer I get a dark screen that says:

Start_Image : Not Found

and nothing else.

I attempted create a boot repair USB stick by using the UNetbootin utility (suggested on this forum). All that happens is a dark screen displaying:

Loading Operating System ...

which seems to hang perpetually.

I created a live USB and booted into that (selecting the "Try Ubuntu" option). I am able to see my existing SSD but I cannot access/open/mount it. I was able to run the bootinfo script (https://github.com/arvidjaar/bootinfoscript) that analyzed grub and the partitions but I do not understand the output.

Here is the output of the bootinfo script. Could a kind soul provide me with some guidance as to what this means, and how I could fix GRUB (or just recover my data at this point)?
