sod's law, i hope you have a backup!
I would start with fresh copy of Recalbox 7.1.1 , check all tutorials on YT , even in French! I don't have time to explain everything as I'm still learning.
Few months back I had trouble with formatting 128gb card but when I finally did it and copied all my ROMs there I lost SD card!
So now I'm back with spare SD 64gb which image I keep in the Cloud as a backup 😉 So even now I'm sitting on Skraper because it doesn't scrape all my images properly but this is subject for another thread
