When attempting to modify field values on a content type with a core Media field in 8.7, I select the field, click the "add media" button, and choose the image from the library (or upload it through the widget, either way produces the same error.) Selecting the image appears to work fine, but after clicking "insert selected," the UI still says "No media items are selected." If you then hit Apply, you get the following error:
The website encountered an unexpected error. Please try again later.

It would be great to be able to bulk update media fields.
