This is just an off-the-cuff guess, but I wonder if you're ironically not blocking enough Javascript? The page loads for me as long as I allow 1st party scripts. I don't have XHR turned on for the site. Iframes obviously don't work, but everything else seems functional: navigation, controls. I don't see a chat option anywhere, I guess I'm blocking that. Just purely a guess, may not be the real issue, and you may already be doing that anyway. But I've run into websites where it feels like half of their JS exists to break the other half, and when I reduce down to only 1st-party, everything suddenly starts working better.
