mtd device must be supplied (device name is empty) - not booting anymore

Question

My Ubuntu 22.04 wont boot anymore, as it get's stuck after [ OK ] Started Tool to automatically collect and sbumit kernel crash signatures.

Before that, it just shows the message in the title and afterwards it stays black with a blinking underscore.

To be honest, I had problems with the booting process from the beginning, having a dual boot - with separate drives though.

One possible issue could be, that I had to delete the syslog file, after a VLC error filled up my whole 2 TB SSD.

I tried already:

• obviously update && upgrade
• fixing the fstab file: changed the errors=remount-ro to rw,user,exec
• boot to live environment and install Boot Repair, used "Recommended repair"
• copy the received error message as follows:

boot-repair-4ppa200 [20220909_1415]

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi of
nvme0n1p2,
using the following options:  nvme0n1p1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file restore-efi-backups
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the Ubuntu 22.04.1 LTS entry (nvme0n1p1/efi/**/grub.efi (** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI**\grub.efi (** will be updated in the final message)
