HTML5 Packaging LowLevelFatal error

I am packaging my project for the game to HTML5 shipping. I am using 4.23 and the packaging is successful for shipping however, when running the game on browser i get the error “LowLevelFatalError [File:Unknown] [Line: 2823]
Failed to load UnrealEd Engine class ‘’.”

I have checked all of my config files for where the “”. could be but came across nothing. I havent found any solution online as well. Please help me understand where this could be at. I have no plugins enabled as well.
