Greetings, @Marc-Neugebauer
The Breach VM is set to a static IP, so it doesn't matter if you make the adapter Bridged, or Host-only, or NAT, or anything else, you won't be able to contact the Breach VM unless your other devices share an IP/Subnet scheme.
So if I have 2 machines, Kali and Breach, they must both be on the same network (bridged, NAT, Host-only, etc) AND they must both have an IP that starts with 192.168.110
and a subnet mask of 255.255.255.0
Breach has a static IP of 192.168.110.140
and a subnet mask of 255.255.255.0
Kali must be set to something like 192.168.110.141
and a subnet mask of 255.255.255.0
Keep in mind 2 devices can't share the same IP.
Once you have that squared away, you should be able to scan Breach.
I hope that helps,
Daniel
