Membership only YT video download refuses to work

[Rouge-Warrior]

I am trying to download a Membership Only video from youtube. I am a member of the channel so I have access to the videos. I have tried following the guide to make a merged .txt file that has both my YT and google cookies as was recommended in the troubleshooting guide. I also went to the Authentication settings and put in my YT username and password so it could use my account with access to download the member only videos. These did nothing for the error I was getting which was, "This video is available to this channel's members." and also "Join this channel to get access to members-only content and other exclusive perks." I am a member of this channel and have put all the information I can think of into tartube settings to get this to work but it just goes straight from pre-processing into error. How do I get it to work?

I don't have a YouTube membership, so I'm not familiar with the process.

You didn't specify which "troubleshooting guide" you're using, perhaps it was this one? Anyway, yt-dlp users would generally type a command like this:

yt-dlp --cookies-from-browser chrome <URL>

...or like this:

yt-dlp --cookies-from-browser firefox <URL>

In Tartube, you can specify any download options you like; in this case, click Edit > General download options.... Then, in the Additional download options box, type --cookies-from-browser firefox.

If that is not the solution, then show me a screenshot (or copy-paste) of Tartube's Output tab after a failed download, with the yellow text at the top visible.
