Tried windows insider for the first time on my hp omen 16

After trying the windows insider in my hp omen 16 even tho i opted for unenrollment from this feature but i couldn't for the past few months and i really need to exit from it as it's been making My laptop hard to use like i can barely do anything not even YouTube been working properly so is there any other option which i can opt for? but not the reset of my desktop as i have some important data in it. Any other option would be preferable.
