SWARM AGENT: Channel registration failed

When I try to build lightning, a widget appears saying "Starting Swarm connection…(100%) and the engine freezes. I can’t even open my desktop while it’s on. I tried to open Swarm Agent myself, It doesn’t open a window but I can see it in the task manager and the Swarm Logs are saying this again and again:
