Cannot purchase or claim marketplace items

Attempting to purchase marketplace items, including Character Creator items, brings up an error: "Sorry, we were unable to complete your purchase. Maybe check your internet connection?". This happens on every WiFi I have tried, including mobile data, and on every device I have tried (Windows 11, Android, OpenSUSE Linux). I have checked multiplayer settings and have suggested WiFi speed.

Of note is that the items are now sorted by price lowest-to-highest, which was not the case before and there is no way to change it.

This happens on both release and beta versions.
