UE 4.27 HTML5 Packaging

I’m working on packaging my game out to HTML5. I’ve found the package launcher module in Unreal Engine, and my game packages out completely.

When I run my project (either via localhost or from the project launcher) it crashes. I don’t really get any error codes or anything - often times I’ll get an error mentioning that the Unreal Network Files Server has crashed or there is a gpu error that occured.

Here is the latest log I got:
Fatal error!
