Lost in Random - mouse appearing during gameplay

I just started playing Lost in Random, and my mouse keeps appearing on the screen when I am playing. I also noticed that it says my controller is disconnected when I first enter the game but I am using a mouse. I have tried to fix these multiple ways and it still doesn't work. I have disabled overlays, refreshed my system, and toggled on and off the full-screen optimizations and nothing makes it go away. it's distracting seeing my mouse all over the screen while playing.
