HI,
I'm getting a similar error in D9.5.7
Drupal\Component\Plugin\Exception\InvalidPluginDefinitionException: The "menu" entity type did not specify a list_builder handler. in Drupal\Core\Entity\EntityTypeManager->getHandler() (line 256 of /var/www/vhosts/drupal9/core/lib/Drupal/Core/Entity/EntityTypeManager.php).
I'm also unable to edit the Admin menu - trying to reorder some of the parent items.

I'm getting the same error as #16 on Drupal 10.2.5
It goes away after invalidation Drupal cache a few times.
But it is indeed a fatal error, the site shows: "The website encountered an unexpected error. Please try again later."
All I did was open the site and try to go to a particular menu from the admin dashboard.
