After a few seconds the page actually loads for me, so I'm not sure if this is actually broken or it is just stalling because it's unable to load an ad script. I'm not seeing any interesting messages in the web console except for one tracking script being blocked a few seconds after the page stalls, https://ads.pubmatic.com/AdServer/js/pwt/159369/5117/pwt.js (and also a blocked attempt to collect Google Analytics telemetry).

We'll have to investigate whether shimming pwt.js helps here.
