Since updating Gin from 8.x-3.0-rc12 to rc13, I can't save existing nodes anymore. Creating the node still works. Using, e.g. Clara as backend theme also works.
I use content moderation if that plays a role?!
The website encountered an unexpected error. Try again later.

I don't know if this is the correct fix - as there are no problems with other themes like Clar0. But https://www.drupal.org/files/issues/2021-12-27/2991986-16.patch → from https://www.drupal.org/project/drupal/issues/3358471#comment-15038304 🐛 TypeError: Cannot access offset of type string on string Active (patching core WidgetBase.php) seems to solve my problem.
