So the plugin that fails is
ATUM Inventory Management for WooCommerce
https://www.stockmanagementlabs.com/
And I think it is using the library version referenced earlier best I can tell.

The User Registration plugin is working however the js error is causing another plugin to fail – when User Registration plugin is deactivated all the other plugins work as they should.
Here are the full URLs for the error
Uncaught TypeError: this.constructor.argsToParams is not a function
