Hello Talitator,
Welcome to Microsoft Q&A forum.
I fully understand how it feels when you are unable to locate and play the game that you bought. Before we proceed, may I have a photo of the issue you are having and the order history that you bought Minecraft to check? You can locate the order at account.microsoft.com/billing/orders. Please remember to remove personal information like the order number, gamertag or timestamps before posting.
Please note that this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas. I'll do my best to help you locate the game and play it. However, if you need more information about your account or purchase, please contact Microsoft Support. Thank you for your understanding.
I'm waiting for your reply.
