Hey Teoman!
Nice to meet you! I'm Darhyl, an Independent Advisor. I'm sorry you are experiencing this on Minecraft.
Just a gentle reminder that we are only Microsoft users like you here in the community. We are not Microsoft employees and we do not have tools to access any Microsoft System.
Kindly try to perform the following workarounds according to the official Mojang Support: https://help.minecraft.net/hc/en-us/articles/44...
"Ensure you have logged into the correct Microsoft Account that purchased Minecraft. You can locate your Microsoft Account on the Microsoft Help Page. https://support.microsoft.com/en-us/account-bil...
Other possible issues could be:
Your launcher is out of date. Update via Settings > About or re-download the Minecraft Launcher. https://www.minecraft.net/en-us/download
You purchased Minecraft under a different email address, or the email address has been changed. Be sure to check your account page to verify your purchase of Minecraft. https://www.minecraft.net/en-us/login?return_ur...
Your purchase was refunded. In this case, you will have received an email from Minecraft and will need to re-purchase the game from the Minecraft Store. https://www.minecraft.net/en-us/store/min...
You just purchased Minecraft while the account was logged into the launcher, or you have not yet chosen a Java profile name. Be sure to restart your launcher and re-try.
Make sure your system meets the system requirements. https://help.minecraft.net/hc/en-us/articles/44... "
