<![CDATA[Opera GX Linux 133 - Widevine loads but DRM is unavailable (Crunchyroll KAT-6005)]]>System:

OS: Zorin OS (Ubuntu-based)
Opera GX: 133.0.5932.81 Stable (64-bit)
Chromium: 149
Widevine: 4.10.3050.0

Problem:
DRM content does not work in Opera GX. Crunchyroll returns error KAT-6005.

Tests performed:

Widevine component is installed and up to date.
libwidevinecdm.so exists.
ldd reports no missing dependencies.
Bitmovin DRM demo reports "No DRM".
opera://media-internals never shows CDM/EME/Widevine events.
Firefox works correctly on the same machine.

Additional information:
strace shows Opera opening:

~/.config/opera-gx/WidevineCdm/4.10.3050.0/manifest.json
~/.config/opera-gx/WidevineCdm/4.10.3050.0/_platform_specific/linux_x64/libwidevinecdm.so

However DRM is never registered and websites cannot detect any supported key system.

This appears to be a regression in Opera GX Linux 133.

So, you're using the deb package of Opera GX?
