Looking at the console it turns out the 2.4.4 update broke GitHub - paviliondev/discourse-locations: Tools for handling locations in Discourse and the 429 error is just because only one error per minute is allowed.
Error: Could not find module
I18nimported fromdiscourse/plugins/discourse-locations/discourse/lib/location-utilities
Is caused by the latest commit in the discourse-locations repository. It probably is targeting beta using a module not available in stable.
I will report the bug in the issue tracker of the plugin, where it belongs.
