Error ([ERROR] Channel registration failed. Reason: An attempt was made to access a socket in a way forbidden by its access permissions}

Hello,

Whenever I build my scene the build status gets stuck on:

0:00:00 Gathering scene geometry…(100%)

Upon double checking the Swarm agent log I see this error repeating indefinitely:

2:37:00 PM: Starting up SwarmAgent …
2:37:00 PM: … registering with remoting service
2:37:00 PM: … registering network channels

I have tried disabling the firewall, I have made sure only one instance of the Swarm Agent is running, I tried reinstalling Unreal completely.

Any help would be much appreciated.

Thanks,
