Comment:

 Issue reproduced with the theme provided above, as well as a simple
 `style.css` + `templates/index.html` theme.

 -----

 - Introduced in [54799]. (6.1.1)
 - Milestoning for `6.1.2`.
 - Increasing `Priority` to `high`.
 - Pinging folks who worked on this to help the ticket move forward:

 -----

 TL;DR - When a block theme does not have a `theme.json` file, the editor
 screen is blank.

 Looks like it might be an issue with [https://github.com/WordPress
 /wordpress-develop/blob/trunk/src/wp-includes/class-wp-theme-json-
 resolver.php#L423-L425 this condition] (removing this early return allows
 the theme to load), or maybe the changes to `::theme_has_support()`.
