I had the same issue and just resolved it. Basically, I tried to disable as much stuff as possible.
Turn off Antivirus software (3rd party software, Windows Defender, etc)
Disable Windows Firewall. There were 3 (public, private, etc). I disabled all.
Ctrl+Alt+Delete, go to Startup tab, and disable every app running.
I don't know which one did the trick... Good luck.
