Mission Control not working

11.0.1 Big Sur, Model A1932

When I do the gesture (Slide with three or four fingers to the right/left) to slide to another desktop, it doesn't work. It is like I have one desktop. When I click the Mission Control button on my keyboard (F3), the desktops don't show up and my screen doesn't zoom out. The desktops only switch if I click the application in dock (If it is currently open in another desktop) or if I get a notification from an application that is open in another desktop, and I can't switch back unless I do one of those two things. My MacBook has restarted on its own a few times before this, I have restarted it a few times before this, and it still is happening. I went to System Preferences → Mission Control, but everything was the same as it was before, I changed a few settings which did nothing.
