Problem with the click inside garrys mod

When I am inside a server or a game of my own does not let me take objects or shoot everything else works fine but the left mouse click this only happens to me when I am in garrys mod

In my 2000 hours of garrys mod I never had anything like that

And tried to solve by uninstalling the game or deactivating all the addons and the problem is still not solved I would like to be given a solution

I had that glitch for a very, very long time. I do not know what the problem is, but I did the following when I remember correctly:

  • I reset EVERY Assigned button I have ever done.
    If that doesn’t work, do the ‘reset to factory settings’. If that also will not work, try to de-activate sync with GMOD and reinstall again.
