Video is black but audio is fine (Waterframes)

So I'm trying to use the Waterframes mod on Fabric 1.21.5 world and whenever I load a link the audio is there, but the screen is black. It's like this with both the large and normal tv, and the frame. The commands don't work for watervision for some reason so that's not an option, and I have all the other plugins installed in order for a YT video to work with Waterframes. The video loads in the "Video player" mode perfectly fine. I also installed the VLC media player to see if that was the issue, and it wasn't.

I've spent the past hour and a half looking up solutions and none of them have worked.

I really need to use this for a video, so if someone could help me out with this, that would be amazing.
