OK, actually I'm wrong. 188743680000/512=368640000 sectors, which
matches the GPT partition. So I'm not sure what happened.
The original error message (bad tree block start, want 1048576 have
6267530653245814412) means content of root node is wrong. 1048576 is
where btrfs "starts". If you cannot read that, you do not have any way
to reach other data. Likely something went wrong copying data.
ERROR: superblock bytenr 274877906944 is larger than device size 188743680000
I don't see this value in the superblock.
This is the third superblock. "dump-super -a" may show it.
What do you get for
btrfs insp dump-s -f /dev/nvme0n1p3
btfs insp dump-t -d /dev/nvme0n1p3
