After clicking on the button "Create notification" I get a white page with the following error:
The website encountered an unexpected error. Please try again later.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
I tried to update to 2.5, but the module is constrained to core 8 now:
- Root composer.json requires drupal/content_notification ^2.4 -> satisfiable by drupal/content_notification[2.5.0].
- drupal/content_notification 2.5.0 requires drupal/core ~8 -> found drupal/core[8.0.0-beta6, ..., 8.9.x-dev] but these were not loaded, likely because it conflicts with another require.
