First of all, I want to state that I looked for similar answers to my problem and it did not work in my case, including here Failed to mount /boot/efi
Here are my system details with desk version: Ubuntu 20.04.4 installed on NUC gen 10 with m2-nvme. No windows, only Ubuntu.
My version of Ubuntu was 20.04.1 LTS and I made a backup with Timeshift (on the mounted SSD, called sda) before upgrading to Ubuntu 20.04.4 LTS. The upgrade went OK.
But in 20.4.4 with php 8, I had problems with the website. I also made a backup here with Timeshift (on the mounted SSD, called sda). After that I decided to restore to the backup from ubuntu 20.04.01. After initializing the restore procedure with Timeshift, I noticed that I had no feedback with "Restore complete" or something like that, and I left the PC on for 1 hour. On restart I noticed the error: Failed to mount /boot/efi, plus hundreds of other errors. Then I used Ubuntu live image and I used boot-repair which gave me positive feedback that is repaired. But on restart it didn't boot. The error is :
[UNSUPP] Starting of Arbitrary Executable File Formats File System Automount Point unsupported

I tried to start the mysql service but it was not possible. I can attach some print screens if needed with what it looks now after trying to boot
LE: Console after boot. https://prnt.sc/NytlEHJ8KUhr
Now my goal is to recover at least the MYSQL database.
Here is the log generated by boot-repair https://paste.ubuntu.com/p/JrwcsnnSpq/
