Workaround: create network manually with:
docker network create sc_net

[JonghunBok]

Do you use daemon.json to set the default bip? I found out that the script that tries to create the sc_net network does so using SUBNET_CIDR = "172.18.0.0/16". It seems if you're using the default bip with a higher number in the second octet, then docker engine refuses to make a network with that subnet cidr configuration. So, if you can't change the default bip, the workaround above seems to be the way to go.
