MapWithAI plugin does not seem to load

[nathaniellukasadam@…]

What steps will reproduce the problem?

Noticeable on startup. Seems to have started happening after I last updated JOSM.

What is the expected result?

MapWithAI features are enabled...
When downloading data there's usually a box to also download MapWithAI data
There should be some MapWithAI entries in the Data menu
There should be some MapWithAI config in the preferences menus

What happens instead?

None of the stuff I mentioned above can be found. Seems like the plugin is not loading at all.

Please provide any additional information below. Attach a screenshot if possible.

I have tried installing+uninstalling the plugin.
MapWithAI is working fine on my Mac running the same version of JOSM.
