I have lost my old Xbox account with my Minecraft Java account

Thanks for your cooperation.

I couldn't login with the original xbox account i had, it shows me a different account that i didn't have even some days ago, the original xbox and minecarft account had been deleted, i searched the name of my minecraft username in a website called "namemc.com" if i could find my account, it says this account had existed prior to the incident, is there any hope for me? The minecraft username in question is "Tazoar_Boss"

Try this:

Download and install the older Launcher marked as Windows 7/8 from this page - https://minecraft.net/download

Then try sign in with the account that owns the game and test it how it goes

I have a semi-similar problem. I bought Minecraft Java edition under my dad’s Microsoft account a little over a year ago which was also being sold with Bedrock as a package. I also have a Microsoft account which only has Bedrock edition. Recently, however, my accounts have been mixed up. The account which only has Bedrock now has access to both Bedrock and Java. The account which has access to both now only has Bedrock installed. The account which ISN’T supposed have Java, which somehow does now, now has my same list of single player worlds and multiplayer worlds. My single player worlds have all my save points and items in tact. On the other hand, because it is under a different account, servers detect it as such. Meaning I have lost all my items, advancements, statistics, etc. Countless hours of progress with my friend lost on my end. The account MEANT to have Java now asks me to buy Java again. I now cannot access my old account with my stuff and irreplaceable items and cannot use my original username. I have no clue how this happened.

I said in the first message that when I log in with microsoft account I don't have access to Minecraft Java, only demo version. My microsoft account only has bedrock edition and the original mojang account seems to be lost.

So you had Java and Bedrock and after the migration you own only Java?

Do you have the confirmation email about the migration?

Waiting for your kind reply.
