SVPTube 2 can´t play V.A videos, only M3U8 on linux

Hi, I recently installed SVP and ran into this problem where I can play any streaming video, but a video on YouTube in V+A format won't play. I tried switching from MPV to VLC, but VLC ends up giving me an error saying it can't open the file.

I'm also unable to run SVP in VLC just through MPV. I have all the dependencies installed, but I still don't know what to look for. Can anyone help me?
