Mouse disappears when I open Gmod

When I downloaded Garry’s Mod and opened it, my mouse disappeared. I can’t select anything in the main menu so I can’t even get into the game itself. I tried uninstalling and reinstalling but the same thing happened. Does anyone know how to fix this? Thanks.

P.S. I’m using a laptop (does this make a difference?)

Disable mouse trails.

Thank you =)
