I still have a black/grey window and i cant log in.

What i have do?

1. By at minecraft.net the Java Version for the first time on 21/1/3
2. download and install the msi installer from my purchase order mail
3. start the installer

After this process i test the compatibility mode, wich i found as a possible fix in the net, and i see the old launcher login window. But with my Microsoft account i get a invalid response "InvalidCredentialsException:Invalid credentials. Invalid username or password."

I buy with my microsoft account the game and i can log in with my browser and see my purchase.

Thanks for help
