@phillxnet it appears after searching the forums that you have extensive experience with btrfs. Thanks for any advice.

[EDIT2] I manages to mount the drive manually using:

mount -o rw,degraded,recovery /dev/sdb /mnt2/MEDIA

as mentioned by @JannikJung0, and it now appears the pool. Do we know why this happens?
