Click Personalize and change theme maybe? Worth a long shot but was Googling around and that fixed a lot of issues on the Microsoft forum that people say stemmed from a corrupt theme file.
Also, some people have to turn off Narrator everytime with cap lock+esc.
I have Mac everything so it’s slightly foreign to me at this point, however I always run into the odd issues myself so I look for the uncommons
Hope this helps in somehow and if not it bumps it to someone who knows better. Gl
