This is an fdisk rather than LVM2 problem.

I.e. your fdisk program moved the start of the partition. That'll pretty
much break any file system that has fixed superblock locations.
Either use an fdisk that matches the defaults used when the partition
was first created or ensure you are using sector display units (looks
like you are - 2048 == 1MiB which is the default used by modern fdisks
from util-linux) and carefully match the start location when
deleting/re-adding.
Btw this is fixable as long as you can still find the correct starting
sector.
