Kanopy is a pay-per-view. Which means the wrapper would have
to be secure, and if your LCD monitor was 1920x1080 or larger,
it would need HDCP (end-to-end encryption to prevent
copying from places like the video card memory if using
the video card CODEC for playback). There is nothing in the
available info, suggesting a root cause. And your equipment is
modern enough to have seamless HDCP.

OK, it's Widevine. Is it worth rolling back the version of this ? Dunno.

widevinecdm.dll and widevinecdm.dll.sig
I am unable to find such a thing as a Kanopy test strip, just to verify
the plumbing works. Any Kanopy entries I find, ask for library card and PIN.

One piece that can break is the MPD (MPEG DASH manifest (dynamic adaptive streaming over HTTP)).
It's much more likely that the Widevine broke, or your screen
resolution has changed since the last time it was working.
