Broken Moon Shell

Don't know where else to ask about it.My moon shell on my r4 ultra just randomly broke. I've had my bf try updating it to see if that was the problem, but it wasn't. It used to work when my bf owned the card. The moon shell just freezes after loading up and no files are visable. Does anyone know roughly what might be wrong? thx

:P no one knows apparently what might be wrong. Oh well.

Did you try deleting the moonshell files then putting them back on the card or something?

Backup all your files and reformat your MicroSD. Re-install Moonshell if needed.
