- Install the standard installation profile
- use a UI Suite theme, like ui_suite_bootstrap (5.1.x)
- in manage display of the article content type, enable Layout Builder on the view mode full
- in Layout Builder add a section from a component, like grid_row_1
- in this section, place the "block" to display the comments field
- keep default settings of the comment field formatter
- save
- error on display

This is an horrible SDC bug...
there is a complex render array generated by the comments block, without any comments.

At a certain depth in the render array, there an an empty array as the value of key "comments".
empty arrays are not considered render arrays, and the whole array structure is then considered not being a render array,
and SDC fails with WSOD.

i propose to create a workaround for that case in ui_patterns, but that's clearly not our role.
We will help users, to keep protected from SDC being too strict :(

or maybe just a core bug...
see Drupal\Core\Render\Element::isRenderArray called from ComponentElement::generateComponentTemplate, line 112. the line Element::isRenderArray($slot_value) is generating the error.
