Forza support site keeps locking up my browswes

Every time I go to login to the forza support it locks up my browser, and it doesn’t matter what browser I am on. I use Edge, but I have also tried Chrome and Firefox, the same thing on all 3. This only happens on support, the rest of the site is fine. I tried to get help from Xbox support, and they just blew me off, saying they have nothing to do with Forza even though it is Microsoft. I have a feeling I will not be able to do anything about this. As far as I am concerned Forza support is nothing but a JOKE anyways.

Not sure what the suggestion here is?

No settings were changed, and everything was find until the other day when this all started. I repeat no settings were changed on my computer, not by me or anyone else.

Now I am getting this.
