Streaming doesn't play content in Win10/Chrome following the latest Chrome update

After applying the most recent Chrome update (Version 113.0.5672.93 (Official Build) (32-bit)) on my Windows 10 laptop, streaming via https://www.xfinity.com/stream has stopped playing content, whether live programs or recorded programs. The channel listing and recorded show inventory are presented correctly, but selecting "watch" in either case results in a blank screen with the three cycling dots; no content is ever shown. Streaming worked fine in Chrome prior to this update.

Streaming does still work correctly in Microsoft Edge. Haven't yet tried Chrome or Safari on my MacBook.
