I've been trying to buy Minecraft Java Edition but it requires me to sign in. I fill out all the correct information to my account, then the captcha comes up once in a while. I do the captcha but the that's it, nothing else happens.

Help me buy Minecraft Java Edition.

I don't know if this is a bug or just a technical problem, please help.

I make a new account but then it tells me that an error occured and I can't sign in. I try to buy minecraft but it still tells me that I need an account.
