Bug Description

Ubuntu Version: Ubuntu Focal Fossa
Package version: 1:3.36.1-1ubuntu4
Expected: Using Screen sharing as expected and often used before
Result: Screen sharing is disabled and can't be reenabled

I have checked the system logs and found this entry:
gnome-control-c[223776]: couldn't list networks: GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: Invalid service name 'vino-server'

Then I have tried to reinstall the vino package in case that something broke in the update yesterday. This did not help so I tried executing the binary manually and this worked:
/usr/lib/vino/vino-server
09/04/2020 10:16:55 Autoprobing TCP port in (all) network interface
09/04/2020 10:16:55 Listening IPv6://[::]:5900
09/04/2020 10:16:55 Listening IPv4://0.0.0.0:5900
09/04/2020 10:16:55 Autoprobing selected port 5900
09/04/2020 10:16:55 Advertising security type: 'TLS' (18)
... (shortened)

The problem might be something related to DBus but I'm not shure.

In my case I can start the service via command line /usr/lib/vino/vino-server
