Issues with light function using rect light

I’m creating an immersive museum using light function with video textures to simulate a projector.
This strategy worked really well with spotlights, but when I try to use it with rect light the texture only appears on a quarter of the screen with infinite lines around the edges.
Does anyone have a suggestion on how I could resolve this? I really didn’t want to do this lighting with spotlights. I’m using Unreal Engine 5.2
