I really have no idea what this is

I have a problem, beat saber runs perfectly fine no matter what mods I use, but no matter the mods, whenever I try to click campaign solo or party, nothing happens. Its as if the buttons to enter these modes aren't even existing. Kind of a weird problem but yeah.

If you haven't already, try and follow the instructions here:

If that doesn't work, I would suggest asking in the #support channel on the BSMG Discord server

Removing the SongBrowser plugin from the Plugins folder may fix the issue based on this Reddit post by u/Rammurg.
