viewport camera wierdly rotated

Hey community , i got a small but very strange issue. I was creating some puzzles, and the main character definetly needs to swithch(posses) between them . However after one of my “switches” the character’s camera wierdly rotated , while i was playing. and then my viewpots’s camera changed as well . like it’s shown on the image.Every time i start the project , viewport’s camera looks like this .
Has enyone faced such an issue ? Any Ideas?
