I hadn't had an issue when upgrading 2.0.6 -> 2.0.8, but the very same error happened to me after upgrading to 3.0.2. The issue was related with a block injection I wrote for my subtheme. Once the block injection was removed from the offending page, everything was fine.

Do you use a subtheme, too?
Can you verify at what occasion/page the error is happening on you site?

Tracking the bug, I found my sub-theme isn't the problem. There isn't much done with that block injection -- preprocessing css values and than having the block processed by some twig in paragraph--block-injection which hands display of the actual block to field--field-block-injection (which is the standard for items block loop).

This is what happens in paragraph--block-injection

{# block paragraph #} <div{{ attributes.addClass(classes) }}> {# block content #} {% if content.field_header is not empty %} {{ content.field_header }} {% endif %} {{ content.field_block_injection }} {% if content.field_footer is not empty %} {{ content.field_footer }} {% endif %} {# endblock #} </div> {# endblock paragraph #}
When I disable the line which engages field--field-block-injection, no problem occurs. Once I enable it, this code should get processed:

{% for item in items %} {{ item.content }} {% endfor %}
Nothing fancy imo, hence I suppose the problem is somewhere in bootstrap 5 -- maybe some code which changed between versions?

It seems the problem is views related. When I use a block-injection which injects a views-block to the paragraph, the screen turns WSOD.
Blocks which show other (static) content, like text, images, … do fine.
