Q Menu error

First of all I’d like to say sorry if this has been posted before, but I can’t find the solution using the search tool.

I keep getting this error and as you can see, it won’t let me open up my QMenu. Any solution to fix this?

I’ve tried renaming my garrymod fold to “garrymod old” thus creating a new clean copy of garrysmod and still the problem persists.

(In this screenshot, I ran the fresh garrymod without any addons etc.)

Any help would be appricated! ^^
