Lost minecraft during migration

Thanks for the info. I understand how important your Minecraft account is for you. I know how that feels. Since your Minecraft game was lost during the migration, it would be best that you reach out to the Minecraft support team for further investigation on their system. You can submit a ticket here https://help.minecraft.net/hc/en-us/requests/new

Thank you.

I have been having the same problem, now in March, and done everything to try and resolve the issue. Even after a complete uninstall and reinstall for Minecraft, (to the point where I erased every file from every registry,) I am still locked out of Java Edition.

At this point, I can only assume this is a problem on Microsoft's end of the Migrations. An error where the license for Java is lost during Migration.

if you cannot access your microsoft account and have 2fa active then they are right all is lost, and as the microsoft account is the account that minecraft migrated too you have now lost minecraft if you cannot access the microsoft account.

Hello FireBird1170,

Thank you for contacting the Xbox Support forums. I understand there was an error during the account migration process between your Minecraft account and Microsoft account. With migration errors, it is common for the game client not to recognize your purchased license. This can be resolved once the migration error is found.

To best assist, please view How to Migrate a Legacy Minecraft Account to a Microsoft Account to ensure no steps were left out during the migration process. If you have already followed through with the full process and are still being met with an error, please open a ticket with the Minecraft Support Team. You may do so by visiting: Minecraft Support - Contact Us.

Thank you,

That's normal, you can't access the old Mojang account after the migration, you need to use the email you used to migrate the Mojang account to, in the launcher you need to select Minecraft Java and then Microsoft login and then use the email you use during the migration process
