No, sorry, there is nothing helping me to confirm my idea in the inxi in this case.
I’m running out of ideas.
I found this old similar thread.
Maybe you could try working in the grub rescue in the same way.
Probably for you hd1 instead of hd0 and /dev/nvme0n1p2 instead of sda2.
I know it can be hard.
Just try if you want.
Just and idea…
