New Minecraft launcher issue

Hello dear Gamer, first it's a pleasure to be able to help you today.

My name is Vinicius.

I am a gamer and independent advisor on the XBOX community platform.

Hey AustinRollins, how are you today? Hope you're well.

Since Minecraft now has one unified launcher on PC, might be just a glitch indeed with the launcher. Since you also have both windows 10 and Java versions on your account, might be just a glitch indeed.

AustinRollins, I advise you to try also to report this possible glitch to Mojang as well:

Hi LucaGamer777, I hope you're doing great despite the issue you're experiencing. I am an Independent advisor and I am here to help you in regard to your concern.

If you're pertaining to Minecraft for Windows, I'm sorry but no, the current Minecraft Launcher on Minecraft is not compatible with the game which means that you will be needing to install the game still through the Microsoft Store or install the new and updated Minecraft Launcher on Microsoft Store/Xbox App to install the game inside of the launcher.

I have this exact same issue. Even though I migrated my account, it seems to think I don't own Minecraft. I can play Minecraft on the old launcher (logged into my Microsoft account) as it seems to recognise that I own the game there. Its only the new launcher that is having the issue and the Mojang website.

If you still have the old launcher installed maybe give it a go as it still works for me.
