You could try to create an image file of the corrupted HiMD with a
software like WinImage [1] and then try attempt to recover the tracks
on the HiMD (working on an image copy avoids further damage to the
medium during attempted recovery) using QHiMDTransfer [2].

If creating an image from the medium fails, it will be very difficult
to recover any tracks since we have no means to access any data on the
medium if the Walkman bails out when trying to read the medium.

Can you actually still see the contents of the HiMD in your file
manager? There should be a folder called "HMDHIFI" containing several
files. If you can still list these, chances are you will be able to
recover at least some of the tracks.
