I just bought Minecraft Bedrock edition for mobile days ago and played on my pc (w10 edition) with the same account. I heard that players who own the bedrock edition are given the java edition for free so I was on the way to claim it. But the issue is when downloaded the w10 launcher for Minecraft the "play" button shows properly and not the "buy" button instead, but when creating the username there's a pop up message saying "failed to create the profile" even though the username is available! I would like to know if I am following the steps wrong or something.

Thanks in advance
