homebrew apps crash when i run them

[bluekirby700900]

I just backed up my 3ds sd card to my computer and no probelms occured but when i try to boot a homebrew app a luma crash comes up, its a diffrent crash for each app. i might know what the problem is but I have no idea how to solve it, the other day my SD card got formatted and I recovered all the contents on it but i think a few things didnt recover properly although i dont think that is the problem because im just getting the errors now after i backed up my sd card
