Persistant Startup crash

Hey there TheZilla, I'm sorry to hear you're experiencing this problem :(

Definitely try running a Packcheck as Drakier suggested (you can check out how to do this here). If that doesn't work, or the Packcheck crashes with the same error code, you may need to remove your content.ggpk file and download it again. If you do this, it'd be a good idea to back up the new content.ggpk file in case it becomes corrupted again later down the line.

There's an old thread discussing this here (please don't bump this thread, I am merely linking it as a reference).
