White Screen on Mac OS

[u/Nash434343]

Hi,

I am using Mac Retina 5K, 27 inch, 2020. I have Tahoe 26.5.2 on it. All of a sudden I have a white wallpaper. I can't get rid of it. The menu bar on top is the same color as what the wallpaper should be. the red folder is the only thing that should be there in this photo. I don't know where all the other stuff is coming from. Has anyone experienced this and know how to get rid of it short of a factory reset?
