<![CDATA[DRM: KeySystem Access Denied!]]>I installed opera-stable 75.0.3969.149 on Ubuntu 20.04 LTS (GNU/Linux 5.4.0-42-generic x86_64) together with chromium-codecs-ffmpeg-extra 89.0.4389.90-0ubuntu0.18.04.2 This combination of previous versions would let me play DRM video content just fine, Since April 10
i get the following error message :

It looks like the latest opera has introduced some problematic code . As a test i installed a older version of opera and chromium-codecs-ffmpeg-extra

ubuntu@ubuntu:~$ dpkg -l | grep opera-stable
ii  opera-stable                               74.0.3911.218                       amd64        Fast, secure, easy-to-use web browser
ubuntu@ubuntu:~$ dpkg -l | grep chromium
ii  chromium-codecs-ffmpeg-extra               87.0.4280.66-0ubuntu0.18.04.1       amd64        Extra ffmpeg codecs for the Chromium Browser
ubuntu@ubuntu:~$

And the same website npo.nl plays all media perfectly.
