fsck does not return anything

Question

My DELL laptop on Ubuntu 20.04 is currently getting stuck on boot after it crashed. I tried to run fsdk on a ubuntu live USB, but when I run the command on my linux filesystem partition sudo fsck -y -f /dev/nvme0n1p3 I only get the following output :

fsck from util-linux 2.34

The fdisk -l command return 3 partitions :
/dev/nvm0n1p1 of 513M, EFI System
/dev/nvm0n1p2 of 732M, Linux Filesystem
/dev/nvm0n1p3 of 952G, Linux Filesystem

Here is the output of sudo parted -l :

Linux says it is 512 bytes.

Is p2 a boot partition and then p3 really LVM? Post this: sudo parted -l. — oldfred, Dec 17 '21 at 16:10
I do not know LVM, but that is what you have. Is it also encrypted? You have to use live installer & mount LVM ( & decrypt if encrypted) and then run fsck on the ext4 volume. https://unix.stackexchange.com/questions/339011/how-do-i-mount-an-lvm-partition/339621#339621 For mounting encrypted see first few lines: https://askubuntu.com/questions/262211/how-do-i-resize-an-encrypted-lvm-to-install-another-copy-of-ubuntu — oldfred, Dec 17 '21 at 17:50
