What I can see is the volume was erased as APFS. (or converted). Did MacOS ask to convert this volume to Time Machine? that would explain this perfectly.

 

You would need to delete the volume and create it again. I am not sure if it is recoverable, but you can scan it wiht the DisK Drill free trial to see what it comes up with (before paying for it, only pay if it appears you will recover your "folder structure" and file names.)

this often means a rogue utility overwrote or initialized the SoftRAID status partition with data. SoftRAID volumes are "write protected" in the partition map area, when the volume is mounted, so this 'should' be impossible, but we have seen it happen several times. Its often disktool (disk utility essentially), (for example during macOS upgrades) but has also happened by other apps that gain root access to the system.

I can take a look, but it may be difficult to recover your data, especially if more than a megabyte of data was written, which may be the case.
