Minecraft Java edition tells me to buy it again after migrating to Microsoft account

Hello again,

so i spoke with Xbox helper and he told me that my minecraft java edition from Xbox Game Pass doesn't exist after the migration and it can't be recovered,

but how is that possible that account can be deleted without any warning, and can't be recovered because it doesn't make sense in my opinion. Also in FAQ about migration there is no information what will happen when you migrate mojang account to microsoft account that has java edition minecraft.

No access to Minecraft: Java Edition after migrating account to Microsoft

I tried everything nothing works

No worries, you can definitely check other workarounds available on their end. Hopefully, they'll be able to see it.

Thank you so much for the detailed information. Kindly uninstall and reinstall the launcher then log in by clicking "Microsoft Login".

I should add that the launcher shows Player as the name on Java edition and my Microsoft Xbox gamertag on the Windows edition on the left
