Adding Lights to scene crashes editor 4.20.1

Hello! So adding a point light or the new Rect light to any of the levels in the project crashes the editor and returns this error: link:Capture

This project was originally in 4.19 and was updated to 4.20.1. Also, the editor was built from source, the release branch on GitHub. I have tried a number of fixes that seemed to have had an affect for other people, like deleting folders in the project directory and regenerating solution or rebuilding the entire engine from source again, but nothing works for me yet. I can still use the project like normal until I try adding some lights, then it crashes. It might be worth noting that I actually have some of those lights in the project already that are carried over from 4.19 and they seem to work fine.

After checking out MaterialShared.cpp in Visual Studio it seems that something isnt included in the declarations but I unfortunately don’t know where to go from here. I shall include a log that is from me opening up the project and adding a point light. link:Log

Thanks!

It seems the easiest solution was to create a new project with the updated editor and then migrate the content folder of our project to the newly created project. Hope this helps at least one person!
