how to uninstall windows 11 insider previews

So, I enrolled in the windows insider program when I first got my pc. I use my pc for games and was playing games like r6 and with the insider its now not allowing me to play the game because of the anti-cheats. I already unenrolled and stopped installing updates, but when I go to uninstall the current updates, it gives me error 0x80070663 when I try to uninstall KB2565063. please help.
