I'm that case if you're on windows press the windows key + r, Type "%appdata%" into the box, go back a folder layer, open LocalLow, find team Quimbly. Delete your saves there
So when you click new game you can play like usual but the issue only shows when you click save or load? I'd still see if there's anything worth clearing in the file area I provided. I've seen this error before and it's almost always due to a corrupt save file.
I think I finally understand. The game save files are not in the game files but in the C drive. It was the save files from a very long time ago that affected me. Thank you, bro
