Hello,
I moved my btrfs to the beginning of my drive & updated the partition
table & also restarted, I'm currently unable to mount it, here's the
output in dmesg.

What command should I run from here?
The filesystem wasn't uncleanly unmounted, likely on an older kernel.

Try mounting with -o recovery
