### Describe the issue you are experiencing
It seems the recently pushed 12.5.3… version of the Samba share addon may have broken something. The addon no longer starts and I get this in the logs.
It first complained that the configuration was incorrect, but once I had ticked the new 'default' setting under server signing it at least tried to start.
