I'm wondering if iBoysoft Data Recovery software has reconfigured your 2020 Band-in-a-Box (BiaB) external drive as a back up or recovery drive. It is pretty common for recovery software to rename a drive that is selected as a back up or recovery drive.

Recovery software typically compresses back up or recovery files in a proprietary file format that can only be written to or read by the recovery software. If my first thought is true that would explain why your Mac is treating the external drive as a read only drive.
