I have a custom list in SharePoint online where I can no longer edit from the item details view in Modern Experience. I can edit in Grid View, and I can view an item or create a new one in item details view, but when I try to edit an item in the details view, all I see is this:

And if I create a new item, it works as expected:
My Form options are set to use the default Edit form:
If I go into Classic View, then the edit form does display as expected.
I've tried changing from classic to modern and back, tried deleting any possible custom Power Apps forms, turned manage content types off and on, tried different browsers, tried deleting all list items and nothing has helped.
When I go into the console view, there are a pile or errors:
Other lists on the same site work as expected. Any idea how to get the Edit Item to display the content again?
