Marionita88 Try deleting the VideoCameraStates folder in Documents > Electronic Arts > The Sims 4. Then set a camera position with ctrl-5 and see whether it works. Alt-5 would clear the position in case you want to experiment multiple times.
If that doesn't help, close the game and the EA App and make sure the EABackgroundService is NOT running in the Task Manager's background processes list. Open [install location]\The Sims 4\Game\Bin\res and delete VideoCamera.ini. (I think it's in the res folder, but it may be directly in Bin.) Then repair the game (EA App > Sims 4 > Manage > Repair), delete teh VideoCameraStates folder again, and test.
