I can't remove the 1.17.30.20 Beta even though I did not choose to enroll in this Beta when I bought the game and downloaded it.

Hi so yesterday on the 4th of August 2021, I bought Minecraft Windows 10 Edition Starter Pack (Bought in the Microsoft Store) and downloaded Minecraft Windows 10 Edition. When I opened Minecraft it was showing a text including Beta (an image is attatched). I did not enroll Minecraft in this Beta before whatsoever. I tried the Methods that were shown on the Xbox Insider Hub but they did not seem to work. If this problem cannot be fixed, I will just request a refund if available
