That's why the mic test demo exists for you to test if the game launches and everything works before you buy it.
Hello, I would like to say that the demo isn't reliable for actually testing the game. I did the mic test demo, I opened settings and made sure my mic worked and everything. It was working perfectly well so I bought the game. I couldn't play the game, it crashes immediately when it comes to my turn in speaking, it also doesn't even let me open up settings. The demo worked just fine; the actual game did not.
