Homebrew Games installed on SD not working

[SK91]

So just randomly games installed on my micro SD crash when I open them

I can still play cartridge games and stuff installed on the system memory but not the SD

there were NSP installed games and eShop ones on there bu neither work now?

Is this a common problem and can I fix it? (my retroarch NSP still works of my card and the homebrew stuff so I don't think its corrupted)

Is your SD card exFAT?

Nope it was always Fat32
anway, I got it working again by reformatting my card and Reinstalling the games
