Thx, I can recover my data.
Solution
1. Do image my btrfs, comand dd on terminal.
2. Mount image, program OSForensiks
3. Recovery lost data. Reclami file recovery or Recovery explorer profesional. Recovery explorer best result.

Please don't post your logs publicly - there is some privacy leakage. I've redacted your download link.
Do you have a backup of the data?
There are btrfs errors on the volume that are preventing it from being mounted:
