I am stuck on a black screen in the new unified launcher

I downloaded the new unified Minecraft launcher; and now, I'm stuck with this stupid screen. I reinstalled the launcher, signed out and re-logged in my Microsoft account in my PC, updated my drivers, but no luck. I also temporarily moved the .minecraft folder somewhere so the launcher won't detect it. I also deleted the old launcher. What should I do now?

I'm so frustrated. I just want to play Minecraft T_T
