Have you tested that this is not an upstream issue or an issue with your configuration?

• I have tried reproducing this issue in Chrome and it could not be reproduced there
• I have tried reproducing this issue in vanilla Chromium and it could not be reproduced there
• I have tried reproducing this issue in ungoogled-chromium with a new and empty profile using --user-data-dir command line argument and it could not be reproduced there

Description

Widevine streams no longer work

How to Reproduce?

1. Install widevine:

wget -c https://dl.google.com/chrome/mac/universal/stable/GGRO/googlechrome.dmg
hdiutil mount googlechrome.dmg
cp -R /Volumes/Google\ Chrome/Google\ Chrome.app/Contents/Frameworks/Google\ Chrome\ Framework.framework/Libraries/WidevineCdm /Applications/Chromium.app/Contents/Frameworks/Chromium\ Framework.framework/Libraries/WidevineCdm
hdiutil unmount /Volumes/Google\ Chrome
rm googlechrome.dmg

2. Go to https://bitmovin.com/demos/drm

Actual behaviour

"The MediaKey object could not be created/initialized
(DRM_MEDIA_KEY_INITIALIZATION_FAILED)"

Expected behaviour

Stream works

For your information: Ungoogled Chromium 130.0.6723.91 with version 4.10.2830.0 of the Widevine plugin works for me. The aforementioned page states "Detected [chromium icon] , using widevine" and the video plays.
This is on Slackware64-current (AMD64 platform) using the natively compiled package of chromium-ungoogled.

As far as I can tell, the issue seems to be specific to the way MacOS apps are signed. Excerpt from the log:

Meanwhile, a very non-ideal workaround:

wget -c https://dl.google.com/chrome/mac/universal/stable/GGRO/googlechrome.dmg -O /tmp/googlechrome.dmg
hdiutil mount /tmp/googlechrome.dmg
cp -R /Volumes/Google\ Chrome/Google\ Chrome.app/Contents/Frameworks/Google\ Chrome\ Framework.framework/Libraries/WidevineCdm /Applications/Chromium.app/Contents/Frameworks/Chromium\ Framework.framework/Libraries/WidevineCdm
hdiutil unmount /Volumes/Google\ Chrome
rm /tmp/googlechrome.dmg
xattr -cr /Applications/Chromium.app
codesign --force --deep -s - /Applications/Chromium.app

This command works on Bitmovin's DRM demo, but it still results in a license error on the Spotify web player.

Spotify isn't expected to work, they have DRM requirements we cannot meet
