The actual error is in core/modules/content_translation/src/ContentTranslationManager.php here:
foreach ($bundles as $bundle) {
$config = $this->loadContentLanguageSettings($entity_type_id, $bundle);
if ($config->getThirdPartySetting('content_translation', 'enabled', FALSE)) {
$enabled = TRUE;
break;
}
}
Something caused ane error like this, during configuration import:
[notice] Synchronized configuration: create views.view.who_s_new in language.es.

The next thing that showed up on another try is the config we tried.
This somehow works even though the node_rss view row processor prevents node templates
from working, so we cannot override this template at the node level.
