Thanks Anshu!
I am on a active directory controlled corporate machine that is using Sophos antivirus, so I can't change settings or do anything there. I'll try safe mode later to bypass it and see if it's blocking the loopback.
I am not using a proxy and I do see the same issue in the latest Chrome version as well. Don't use Edge so I can't speak to that status.
I have run the commands you mentioned above and will send them via email as you requested.
