When Disable Field is enabled, I cannot add any new item into select list field in a content type.
I have two Drupal instances in the server, it works fine in the old instance but the fresh installation doesnt work.
When i check log, I see the following Message:
LogicException: The database connection is not serializable. This probably means you are serializing an object that has an indirect reference to the database connection. Adjust your code so that is not necessary. Alternatively, look at DependencySerializationTrait as a temporary solution. in Drupal\Core\Database\Connection->__sleep() (line 1920 of /var/www/isms-uk/core/lib/Drupal/Core/Database/Connection.php).
And under Backtrace:

I can't reproduce this error. Is there possibly another module that is interfering?
I had the same issue on my website.
Found out that using DependencySerializationTrait solves the issue.
