I NEED HELP

[HAHAHAAHA172]

My sd card which has my save file just decided to stop working and now I can't get those files because the gdrive saves are hidden (possibly overwritten also) and my sd card is still working but is unstable on my phone so I have two options either the dev help me get my save file from the gdrive or anyone can suggest on how I can retrieve that save file from the sd card using my pc.

It's a pokemon black save file btw it's the only game I play in lemuroid because I mostly play gba games in other emulators. Any help would do
