It's a camera clipping problem. Your clip start and end are too far apart. I can't find an exact duplicate but you should find the options there https://blender.stackexchange.com/a/4947/86891 make sure there is less than 10^7 or 10^8 difference between start and end

I sometimes experience this as well. What helps most of the time is to change Clip Start and End in the View options (as @Gorgious said). Sometimes I also hit Numpad "." to center on selected objects or Shift + C to Center Cursor and Frame All.
