Multicam not working properly in 23.5 (build 56)

I am editing on a Mac M2 STUDIO PRO WITH 96GB RAM, OS VENTURA (13.5). PP 23.5

Multicam was working fine for two months but now is suddenly not performing properly.  When I enter Multi-Cam mode (shift+0) my 10 camera grid does not appear.  I only see the camera that is currently selected.  If I start clicking on the window it will pop into the grid, but in doing so it chooses whatever camera I unknowingly clicked.  Does anyone have a slolution to this issue?  People in other forums are experiencing it too but noone seems to have a fix.  Should I go back to an earlier version of PP?
