I found the “issue” started to happen after VirtualBox 6.1.26.
The way to solve is creating a new file at /etc/vbox/networks.conf on your macOS with content
* 10.0.0.0/8 192.168.0.0/16
* 2001::/64
Make sure including the asterisks *. Then the issue should be gone.
Regarding the networks.conf content, it can be found at https://www.virtualbox.org/manual/ch06.html#network_hostonly
