Lighting and shadowing problems when switching from 5.4.4 to 5.5.0

Hi,
I am developing a game, after moving my project from 5.4.4 to 5.5.0 I started to get lighting and shadowing problems. While there were no problems during development, right after I started playing the level in the viewport, unexpected square-shaped shadows started to appear at some points and these shadows appear in different places as I move. If there is a solution for this, I would be glad if you could share it.
