Mono script is missing?

I seem to be missing a script called Mono Script. for some reason I don’t have it and can’t find a copy of this script online either. if anyone could give some assistance or insight on this matter I’d very much appreciate it.

This happens when you add a component to the gameObject, and later remove the script from the project. The component still exists, but the script it’s using does not. Unity can’t tell what the script name was. If you don’t need it, just remove the component. Otherwise you might want to figure out, what script it was and restore it.
