Welcome şahan byk,
I'm sorry Minecraft isn't working for you. That's really frustrating, especially on a bad day. Since you're using a child account that your father manages, some settings in Microsoft Family might be stopping Minecraft from opening.
First, could you tell me:
- What exactly happens when you try to open Minecraft in the Minecraft Launcher? Do you see an error message, or a message asking you to buy the game?
- Is your account a child account in your father's Microsoft family group?
- Did anything change recently? For example, a new family member was added, someone left the family group, or your father changed settings in the Family Safety app.
Looking forward to your update.
