Same issue here, with Netflix, Disney+ and Prime Video.
There is a plugin with instructions for Linux users ↓, but nothing for Windows users, as far as I could research.

Have you consulted faq#how-do-i-install-widevine-cdm?

[y0LAs]

Yes, and I did it again after your response, but couldn't find any working solution.
For Windows, it leads to https://chromium.woolyss.com/#widevine, where it says that you have to install the Widevine plugin yourself, but on the official website, you can't download it anymore : https://www.widevine.com/download/videooptimizer Broken link, no downloads anymore on the website.
On https://chromium.woolyss.com/#widevine, it also says that you need to go to chrome://components/ and check that "Widevine Content Decryption Module" is an other version than 0.0.0.0.
But it is on Ungoogled Chromium, and clicking on "Chek for update" and waiting doesn't work.

Did you manage to make it work on Windows?

Looks like the widevine at https://dl.google.com/widevine-cdm/4.10.2710.0-win-x64.zip is a very old one & manifest gives errors when I uploaded it to ungoogled-chromium.
