Not launch VPN on Mac suddenly

I am using MAC OS Monterey 12.72, and since receiving a notification about a Norton update, Norton VPN Secure has stopped launching. All other functions are still active. I vaguely remember being prompted to enable a new feature or change something in the extensions as part of the update process, but I’m not sure. Anyway, the VPN won’t start, and I’m having trouble with it. I’m not very knowledgeable about PCs. Please help.
