start menu doesnt open

[Drjones141]

note: i have installed mcafee
The windows button wont open making microsoft edge unusable and a few other things, like the search bar unusable. Anyone have a fix for this other than refreshing or resetting or changing or removing any files?? When I right click it a gray menu pops up but if I give it a normal click i get a loading wheel then nothing.
