Is there any reason that I can’t move my player around by clicking and dragging from the top freely like I was once able to? This is a new problem. Closing and opening usually doesn’t solve it. I think PC restarts have solved it for a limited time.
So it turns out my Windows Desktop Integration System Window Controls was somehow disabled even with it switched on. By turning it off and restarting it worked by clicking and dragging from normal top area of UI. Then, when flipping it back on again, it continued to work with System Window Controls bar now re-enabled and again made visible.
