Comment (by bijayyadav):

 I installed 5.3 beta and copied `twentytwentytwo` theme and renamed it
 `twentytwentytwo!`. After that on the backend, I clicked on Appearance >
 Editor and the page was blank. There are two errors on console:

 * http://localhost/beta/wp-
 json/wp/v2/templates/twentytwentytwo!//home?context=edit&_locale=user 404
 (Not Found)
 * Uncaught (in promise) TypeError: Cannot destructure property 'id' of
 '(intermediate value)' as it is null. - http://localhost/beta/wp-
 includes/js/dist/edit-site.min.js?ver=dd4604f4d44cfa19261ecfc79f1e6f06
