Saved custom cameras stop working

I created custom cameras and assigned them to game controller and keyboard. Everything works for few days and then cameras stop working. I checked camera settings in the sim and I see all custom cameras are still assigned correctly but they don’t work in the sim. If I reassign cameras back again it works but for some time and then stop working again. So I stuck in the loop. Any suggestions?

I also read that custom cameras can be saved/backed up in Xbox account. I do not have an Xbox account. Is there another way?
