Comment (by sabernhardt):

 Somehow the `$block_attributes` variable is `null` in
 `wp_apply_alignment_support()` for your site, and the stack trace mentions
 the Site Logo block.

 [https://core.trac.wordpress.org/browser/trunk/src/wp-includes/block-
 supports/align.php?rev=56382#L48 Line 48] could check `is_array()` before
 running `array_key_exists()`, but it would help to know how the
 `$block_attributes` can be any other type.
 {{{
 $has_block_alignment = is_array( $block_attributes ) && array_key_exists(
 'align', $block_attributes );
 }}}
