Parrot SSD wont boot

I have no idea why suddenly I cannt boot (laptop Lenovo Ideapad 320S, Parrot OS 14.11 sec encrypted)
After I got Grub Rescue I tried first the Boot Repair disk and I got the following URL for help: Ubuntu Pastebin
Then I followed the instructions in TUT> Boot fix for encrypted SSD on Parrot(2021) very carefully but when I tried with sudo grub/install /dev/sda2 got the error: cannot find EFI directory.
Very confusing. I appreciate any hints.

  • ParrotOS iso in use:

  • Application used for flashing the iso:

  • Logs/Terminal output (use pastebin or similar services):

  • Screenshots:
