I see Release 2025.04.30 was made available on yt-dlp. If this is the one you got then there seems to be hope that this is fixed.
While each VRC user could go through the steps of downloading and installing it isn’t really practical which is why VRC needs to incorporate the latest versions into their release.
I’m going to install the update on my API server and will give it a test shortly. Hopefully it is all working again.
