SD cards corruption

hello…I got to read the SD in a windows system, the pc has detected the volumio SD. I’ve took advantage of it and I made a backup of that SD, then I flashed using the backup. However the RP4 got stuck loading volumio system. The only one solution was flashing a clean version of Volumio 3 on the same SD…it works, but again I lost all my playlist.
In a last breath to try recover all the playlist I set up a UBUNTU virtual machine running on windows, (I’ve never used ubuntu o linux before). Ubuntu system recognize the linux volumio partitions on the SD, but It can´t read them.

I´ve have been two days trying to recover the playlist from the SD backup with any good result. it has been impossible. What´s the point of saving backups of your playlist in the SD when you can´t access to the information…
any suggestion ?
