What do you mean not working ?, no detection or the downloads are failing. You have to be more specific about the issue.

Sorry, the path I'm usually downloading to is on an external drive, and just today I've realized that somehow it was disconnected! Now everything is working smoothly as it should 🙏🤩

I feel the same way. I updated VDH to 9.5.0.2, but nothing is detected with Firefox 139.0.1.
With Chrome, detection and downloads are possible, but it is limited to 360p.

After not needing it for quite some time, I used DH yesterday for the first time in years. It worked fine, but had the QR watermark. I decided to buy a license. Once the license was activated, I restarted FF which had updated itself. Now, DH doesn't recognize the same YouTube video that I downloaded just yesterday. One thing. The video shows an age restriction and requires logging in. I don't "think" that was there yesterday.

yes, sorry, there are still issues with age restricted videos.

I also have the same problem, it generates the video, but when downloading it asks to install Coapp, I install it, but then it doesn't download and asks to install Coapp again, and it stays
