I always love working with partitions because of the knowledge it gives you, but it is also certainly dangerous and from time to time it is unnevitable to suffer an accident. In any case I always try to do this type of operations with parted and if possible with GUI (gparted).
Being in the photo situation, can’t you make a fsck as the error messages tell you?
fsck /dev/nvme0n1p2
If not, the most practical would be, IMHO, to boot from a rescue live, e.g. www.system-rescue.org/Download/Once booted, you can lift the graphical interface with startx and do with gparted the operations you need on these partitions.
