Use the automatic tagging process on various content.
In general this process should skip errors (like this and other related to extractor, timeouts etc) and continue because there is no command line or other mean to tag content leading to require constant human supervision to restart the tagging batch process.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
For this add condition on line 111 at /src/PowerTagging.php
if ($form_display !== null) {
$specific_widget_type = $form_display->getComponent($field_definition->getName());
}But need to think on else condition.
