Hiiii, just solved so imma give you step by step instructions k?
1- Press windows+r
2-Type this: %appdata%
3-A folder should have oppened
4-Enter the folder that says Roaming
5-Enter the folder that says FunkinCrew
6-Move or delete Funkin1.sol
PD: The problem was caused because of something with your bindings, deleting Funkin1.sol resets all data of the game, so that's why it solves the problem
(Make sure to rebind your keys more carefully)
Have an excellent day!
