IWP items missing in editor

none of my pre-existing items are appearing in the Commerce menu for any of my worlds.

If I try to make a new item, I see it listed for a split second then the list is empty again. This seemed to be working fine yesterday morning.

When I look up all my items for my account at https://horizon.meta.com/creator/avatars I see all my IWP items are present. But for some reason are not registering in the editor for me.

Any ideas? I've done a quick search and can't find any prior reports of a similar issue.
