I'm having huge problem with inputting

So the issue I'm having is that the game can't seem to detect me right-clicking correctly; this makes it so that I can't ping, I can't use spells without quick cast, and I can't pan my camera immediately to a place in the minimap...

Note: If I press g(the ping button) then spam right-click, eventually the input will register, so I know that my right-click works sometimes.

I've tried many things to fix this issue:

I tried it with a different mouse, and it's still the same I tried uninstalling and re-installing league, and I still have that same issue I tried playing on my other account, and I still have the same issue I tried following some tutorials online, but maybe I haven't found the right one for my issue...

I really need help with this, because it's making my experience playing so much worse.
