The image in the project doubles after experimenting with light

Hello,

I’m trying to study the lighting in Unreal, but as a result of my adventures after the last launch this morning of the project, I got this problem in some places on the location.

I’m still not so well versed in all the nuances of this part of the Unreal, so if someone knows how I can fix it, I will be extremely grateful for your help.

The latest Nvidia drivers are problematic. If you are on the latest can you roll back and try again?
