Triangular Shadows on Windows & Doors affecting in Game Lighting Shadows

Why are the doors and windows showing triangular shadows in my game? Could there be an issue with the ea meshes? This is affecting the lighting shadows in game and causing them to have a jagged edge to them. I have attached the pictures to this forum. 

Things I have done to resolve with no success:

Repaired the game

Removed my mods folder

Uninstalled the game

Reinstalled the game 

Settings:

I play on ultra settings

edge smoothing is on the highest setting

I play on a beefy gaming pc with an RTX 4070 graphics card. 

There are no mods in my game. 

Thanks in advance for the help to resolve this issue.
