My Game Pass has been deleted. how i get again?

Hello Microsoft team, I am 12 years old. My father had purchased a Game Pass subscription for me, which we paid for on a monthly basis. Thanks to Game Pass, I was able to access Minecraft. One day, I opened the Minecraft Launcher, but I couldn't get into the game. I thought to myself, "What is going on? I’m already having the worst day—please, don't let it get any worse!" That was when I discovered that my Game Pass subscription had been removed. what can i do?
