I also got this error moments before I submitted my game. I fixed it for me after messing with the configurations a bit. Unfortunately, this seems to be more of an engine-related problem, as Godot 4 doesn't handle browser games very well. I had uploaded the executable just in case something like this happens. It's still a bummer though
