How do i leave the Minecraft Beta on windows 10?

In this case you will have to contact the developer of the game Mojang to further check your case and see what's going on

How to Leave the Beta

1. On Xbox One or a Windows 10 PC, sign in with the account that registered for the Minecraft Beta and launch the Xbox Insider Hub.
2. Navigate to Insider content > Minecraft (or Minecraft for Windows 10 on PC)
3. Select Manage.
4. Use the radio button to select Unenroll (Leave this preview), then select Done.
5. Wait an additional 30-60 minutes after unenrollment completes (Pending no longer appears in the Xbox Insider Hub).
6. Uninstall and reinstall Minecraft.

I believe you may be enrolled in Minecraft Beta in the Xbox Insider for PC and you need to un-enroll. Do not rejoin the Beta if you do not want the Beta.
