Heise.de has reported that users of Intel's 11 and 12th generation core processors cannot play UHD Blu-ray discs due to the halt of support located in the SGX instruction set. The reasoning for Intel to stop allowing for the playback of the Blu-ray technology on those two generations is that the system believes that there is a security vulnerability at hand, causing the disc to be unable to be read.

The playback of UHD Blu-ray discs utilizes hugely high requirements. First, the disc searches to find if it meets the compatibility requirements given by the system processor. Then, the disc must ensure that several digital rights management technologies are in place, such as advanced access content system (AACS 2.0 ) copy protection, high bandwidth digital content protection (HDCP 2.2), and Intel's SGX technology.
