Can not select when i click but selects when i use a selection window

when i click on a line or curve or anything it doesn’t select anything, but if i drag a window over it it selects everything fine. how do i fix this I restarted my computer and it still doesn’t work. Btw rhino 8 on windows.

I’m having this same issue.
No objects or layers are locked, and no selection filters are on. I also cannot snap to objects.

This happened in the middle of a session, and continues even after restarting my computer and relaunching Rhino.

Obviously, this really limits to ability to model. Very strange behavior.
