Then clear your oneui launcher data and cache if doesn't help reset your device

Your application didn't remove just your app you have one your home screen will remove it's just set to default only

I too received it on M30, totally non-sense from Samsung, ads useless apps without your confirmation. Really shameful from Samsung.
