Symfony\Component\Routing\Exception\RouteNotFoundException: Route "entity.block_group_content.canonical" does not exist. in Drupal\Core\Routing\RouteProvider->getRouteByName() (line 190 of /app/public/core/lib/Drupal/Core/Routing/RouteProvider.php). Appears when editing a blockgroup e.g admin/structure/block_group_content/{name}
It seems blockgroup claims to have a link template, but actually, it doesn't exists. Patch attached that should fix this
Needs review

Not all content is available!
It's likely this issue predates Contrib.social: some issue and comment data are missing.
I tried deleting a block group manually. It worked like a charm.
But when I exported my configurations and imported them using drush config:import, I got the same error repeatedly until I applied the patch provided in #2.
I am using block group 2.0.0 and Drupal 10.2.
