Upgrading WebGL from 2019 to 2022 Module.asmLibraryArg missing

[unityruba]

Would you happen to be using an external jslib like the one described here?

Uncaught TypeError: Cannot redefine property: asmLibraryArg

I found the cause of the problem. It was an external jslib plugin (https://github.com/kongregate/Unity-WebGL-Utilities). It worked after removing it. Looks like it's conflicting with 2019.1. If you're publishing your game in Kongregate, you might have come across this plugin.

It seems that others ran into this and had to remove it since it wasn’t compatible with newer Unity versions.
