Btrfs unable to delete folder

Hello!

I’ve read I had to ask for support about btfs issues before run any check --repair.

Here we are. I have a drive (already two) with undeletable folder. Folder can not be deleted by ‘sudo rm -rf /’ nor by calling ‘btrfs check --repair’ on a file system with no error reported. I’ve created a snapshot of a drive for further examination.
