Does it still happen in Troubleshoot Mode?

I tried both and they still will not load

Works for me. see screenshot Who are you using for DNS? What security software are you running? Does it happen under a different windows account?

If Windows Pro version, try testing in Windows Sandbox (VM) to see if you have the same issue. https://www.howtogeek.com/399290/how-to-use-windows-10s-new-sandbox-to-safely-test-apps/

Does it still happen with default settings in a new browser profile? An easy way to test a new profile is to install Developer Edition and see if it happens there or refresh your existing profile. Make sure you stay signed out of your sync account when testing.
