Booting with no RMU Connection problematic

I don’t use Dolby Atmos, but when I boot up Nuendo 10 it will freeze showing “Intializing: Nuendo RMU Connector for Dolby Atmos”. Most times it will never finish booting up from there. Nuendo shows “no RMU device” but still seems to try to connect.
How do I stop Nuendo from trying to connect and then freeze and eventually shut down without ever booting up? Object mapping shows “no RMU found”.

It seems to be a firewall I have blocking ports. Disabling the firewall allows Nuendo to boot without the error.
