Burger menu disappeared after skinning

[Baalial]

I am using 10.9.10 of jellyfin-server and jellyfin-web on Garuda Dr460nized (Dragonized) which is also fully up to date as of a day or two ago. Both server and web were installed via the AUR, which has always worked fine and worked fine on this machine until the skin borked it.    

I applied a skin using a custom CSS line that automatically downloaded the skin and applied it - while the skin works for everything else, it removed the "burger" menu on the top left of the web view in Firefox - I haven't tried other browsers because I only use Firefox for anything with passwords. If I hit F12 and hide the custom CSS it reveals the burger menu but I have to navigate with the keyboard to select it and then I can use the mouse to select the dashboard and change the skin. I can't remember the name of the skin I originally applied, but it was from the creators github, and their skin(s) are in the skin manager plugin so it's nothing malicious. In fact, their own screenshots show the burger menu missing exactly the same way.

I have searched for ways to navigate that may reveal the menu to no avail - I'm forced to admin my server via the F12+hide CSS method which is a major pain in the butt. Applying other skins still works if I do this, but none of them bring back the burger menu, even the original/default skin. Is there a way to reset the entire interface to default without wiping my server entirely? I'd love to use other skins but not at the expense of losing the most important part of the web view.

The android client, jellyfin-media-player on linux, and the Roku client all still work fine (the Roku client is extremely basic and doesn't allow any customization at all) and the Android/linux clients show the skin - but still no burger menu.

Any help would be appreciated. This is my first post, if the attached image isn't visible I will try to post a link.

You'd have to go to the skin creator's git and report this to them. They may have accidentally hidden the element for the burger menu. But there is nothing we can do about it.

You could manually apply the CSS in their download link, minus whatever is hiding the burger menu.

So there is no way to reset aside from full deletion then?

Reset the CSS?

/etc/jellyfin/branding.xml

Replace whatever is in between <CustomCss> should be deleted and replaced with <CustomCss />.
