Left and right click options bug

I got an annoying bug…
every icon you can press to have further options doesn’t work for me or work after I click like a hundred times…
for example, I can’t open any blueprints because it doesn’t let me press the option to create one.
same happens for the file menu that doesn’t open.

also, once I reach the blueprint section, if i reach that, I can’t create a new node because the option doesn’t pop up.

I wasn’t experiencing that kind of issue using UE 4.8 and the issue is probably not my PC cause i got a i7-7700 and a gtx1070 card

If you have any solutions let me know before I give up on UE4
thanks
