Scheme says ready but won’t go through?

I’ve been having this problem for a few months at this point, I can’t figure out as to why. Maybe because my graphical settings are set to the lowest? What exactly is wrong with my game? Is anyone else experiencing the same problem where it reaches to ready, but never goes through? It seems no matter how long, this bug never goes away. Or if at some point executing the scheme became a manual process, I’m not sure. It never goes through for me, and I am just confused as to what to do to fix this problem.
