Third Person BP camera doesn't rotate with mouse unless mouse is down if the level it is in is loaded from an other level

I’ve created a level that uses a custom Gamemode BP that displays the title menu, and when you click ‘Play’ it loads an other level that uses the correct Gamemode BP for the Third Person BP.

When I launch the game directly into the third person level, it works, but when loaded from an other level it requires me to hold down the mouse in order to rotate the camera.

this happens to me too frequently, I don’t know what goes wrong
