Vpn shutdown down new iphone

I have a new iphone se. iOS 14.1

I loaded the VPN app from Norton360 onto my ipone. It causes my iphone to shut down as often as 3x per 5 minutes. The phone shuts down, even while I am on a phone call, then phone reboots. As soon as I trashed the VPN from my iphone, the shutdowns stopped. Any solutions?
