Hmmm. I'm not topic starter, but I changed default browser from Yandex Browser (Chromium) to Edge and login was successful.

Same problem on alpha

Hello.
What need I do with archive from github to play? When run faf-uid.exe nothing changed.

Read about off all devices except you current audio device. It helps for me.
Plus update nvidia driver (read about problem with nvidia in old topics)

Была похожая хрень, помогло вместо Яндекс браузера поставить Edge браузером по умолчанию.

У меня не работало пока не поставил EDGE браузером по умолчанию. Яндекс браузер просто не давал запуска фаф клиенту.

В дискорде Infernal FAF есть тема "купить-игры-steam", там казах GYNZAN помогает приобрести ФАФ через подарок. Сейчас порядка 600р цена.
Вы переводите ему через QIWI, он покупает SC:FA и дарит Вам. Пока это работает.
Надеюсь тут не банят за ссылки.

I'm too. Don't had this problem months ago.

Hello. Why in my FAF profile in statistic only count of played games, but no other statistic and achievements?

Hmmm. I'm not topic starter, but I changed default browser from Yandex Browser (Chromium) to Edge and login was successful.

We can try to do a remote debug session, if you interested in it. And if I can install all necessary soft...

UPD:
Changing default browser to Edge help to login.
