After await page.setRequestInterception(true) every request pauses until the handler calls request.continue(), request.respond() or request.abort(). A handler that returns early on some branch, or throws before resolving the request, leaves that request hanging forever and the page hangs with it until the navigation timeout fires. The symptom is a load that never completes rather than an error naming the handler.
Write the handler so that every path terminates the request, including the catch block, and remember that calling two of those methods on the same request throws an error saying the request is already handled. Interception also disables Chrome's HTTP cache for intercepted requests, so timings measured with it enabled are not representative. When you only need to observe traffic, listen to the request and response events without enabling interception at all.
