Comment (by wildworks):

 > In addition, if `WP_Theme::is_block_theme` is called too early, a
 `_doing_it_wrong()` error will now be thrown.

 [https://github.com/WordPress/wordpress-
 develop/blob/7475126055ddf7b9fd6c303d2468676926b762f0/src/wp-includes
 /class-wp-theme.php#L1581 This early return] might cause problems if you
 have a theme or plugin that is calling `WP_Theme::is_block_theme` too
 early.

 For example, if the following plugin is enabled:

 {{{
 <?php
 /**
  * Plugin Name: Block Theme Test
  */

 wp_is_block_theme();
 }}}

 At this time, the site editor appears to display a black screen.
