Your ROM is corrupted

Citra was working fine for me for quite a long time, but this popped up recently when I was trying to load a file. Some of my games such as pokemon sun and ultra sun can no longer work either (there’s a red sign beside the file). Does anyone have any idea how to fix this problem?

As the popup says, your ROM is corrupted. You’ll need to redump it. Please make sure your GM9 is up to date and you have enough space on your SD card to perform the dump.
