I tried this and it did not work.

lol, not sure how/why but this tip actually worked for me... 🤷🏼‍♂️

Update. This worked until I rebooted my machine. Once I rebooted it reverted to the original error.

I don't have Cisco AnyConnect but still have the issue. Are you suggesting any VPN app might be the issue? Why would the VPN affect Intel Macs but not Apple chips?
