The player does not start at the camera location or even the Player Start location.
There is no code in the level BP. I have tried opening other levels and trying other characters, but it behaves the same. Even tried playing as a standalone. In the Output log, there are no errors or warnings. I am using UE5.1
The player will not spawn predictably if there is something in the way. Have you looked at the view in player collision mode?
Also, if you have placed a player in the level, that will be used ( if set to possess ).
Yes… There is nothing in the way of the character spawning
Did you specifically use collision view? 
Are you using a default player controller?
Yes, I did use collision view, and the player controller is the default one. I managed to fix the problem by migrating every file to a new project. Now it works.
