Failed to load IL2CPP is not a bug! Please watch

This means the PokeOne.exe or GameAssembly.dll are missing, this is due to your antivirus deleting them. Recently windows defender and other antivirus decided they would flag the program we use to encrypt the game client to prevent people from figuring out how to make bots.. Its easy to fix, you just need to whitelist/exclude/allow these 2 files or the game folder in your antivirus and it will work.
