Edit content type page crashes while saving...

When I click on a new content type definition that is empty, and click on save, the page crashes.

System.NullReferenceException: Object reference not set to an instance of an object.

I think this was fixed last night via PR #14837. If you are using 1.8 previews, please test with the latest

Fixed in 1.8 (main branch)
