Blu-ray UHD discs are no longer supported on latest Intel PC processors.
Intel has eliminated support for SGX, a DRM-related security mechanism required to play UHD Blu-ray Discs, from its 11th and 12th generation chips.
Intel's 11th Gen Rocket Lake (Core i-11000) and 12th Gen Alder Lake (Core i-12000) processors no longer support SGX (Software Guard Extensions). SGX, in conjunction with HDCP 2.2 and AACS 2.0, is necessary for UHD Blu-ray playing on PCs. This implies consumers will be unable to use the latest Intel-based PCs as 4K HDR Blu-ray players.
CyberLink, the maker of the PC application PowerDVD, has stated that the elimination of SGX implies that its software would no longer support UHD Blu-ray playing. While Intel's 7000, 8000, 9000, and 10000 series processors continue to support SGX, CyberLink warns that feature may be discontinued in future versions of the Intel driver.
"Intel SGX support has been discontinued from 11th generation (or newer) CPUs, and it may be removed from future versions of Intel drivers or utility programs (e.g., the Intel SGX and Intel Management Engine driver and firmware). These modifications may result in the loss of support for Ultra HD Blu-ray movie disc playback on these devices "CyberLink stated in a Frequently Asked Questions document.
"The elimination of the SGX capability, as well as its compatibility with the current Windows operating system and drivers, has created a significant hurdle for CyberLink in terms of continuing to offer Ultra HD Blu-ray movie playback in our player software. As a result, CyberLink has determined that it is no longer practicable to support Ultra HD Blu-ray playing on newer CPUs and Windows systems."
Intel has supported SGX since Skylake (Core i-6000), however, security researchers discovered multiple flaws in the technology, which is likely why Intel is discontinuing support. AMD processors do not support SGX, it appears that support for UHD Blu-ray movies on PCs has come to an end.

it's only the UHD Blue Ray, the normal one still work (even on AMD CPU by the way)... btw even BR can't handle a real UHD with everything shiny (but i agree that with lower quality sound and a bit compression here and here... they fit on it and it's better than BR), only download can do it.
More and more DRM problem each year...
Technicaly when the company that have the right over a classical or old movie, put DRM on the digital reworked version, it's always a drama.
Cineclub (ok it's not UHD but the DRM problem is the same) sadly mainly better use pirated or home made illegal version than DRM version.
DRM doesn't protect movie (just take a look on the quality of the 4k illegal download just after the release of a 4k movie) but really bother end user with things like this,
and anyway a compulsive pirate, would not bought, the game, movie or music even if the price were low... It's a fake protection only made to do money.

Never understood these things, pirated version will be out there despite DRM. They are only making life hard for the good folks who want to do everything legally. Fortunately for those who are looking, there are several options to play these discs on PC since the beginning (the BD drive part is a little bit complicated though).
I remember that even with fully legal playback, you can not output the higher def audio via an USB soundcard or DAC, because there is a thing called Protected Audio Video Path, and USB is "not safe". So you can only use eg.: Dolby TrueHD via HDMI or via some integrated audio on your mobo any other method will get only Dolby Digital and DTS (these things are also solved by the "playback helpers").

Even if you have the DRM capabilities in the CPU you still need to buy licensed software to be able to play BluRays :| I found that out when I bought one years ago for my dad who wanted to move away from multiple devices and use his media center PC to view blurays on.
