So i was going right to see if there is grandma or not but suddenly it came up with that error it could be a glitch or a bug
That's interesting... I downloaded, extracted, and tested the game out again myself and I didn't run into this issue.
Maybe it's a glitch with how it extracted or downloaded onto your computer since that type of error only comes up when there's a missing file. Can you try downloading the game again?
This is so weird, I'm sorry!
