Still happens on Monterey (12.2.1) with MacBook Pro M1 2020. I noticed first this with time machine, so I reformatted my external 1TB Seagate drive as encrypted, case-sensitive APFS to do backup manually, but it is still happening with or without a hub. The disk ejects randomly, or it can become extremely slow even to list a directory (having maybe a dozen entries only).
