Help Please - Running hass for the first time is hung-up

I’m new to this but I followed the steps to manually install HA on a Raspberry Pi Buster. I’ve tried running hass a few times but it hangs up at “Starting Zeroconf broadcast” every time. Any ideas on why this is happening and how I can fix it? Thanks
Update After wiping the card and re-installing everything I enter “hass”. It is now hung-up at “Timer:starting”.
