Installing Norton on OS Sequoia - not possible to launch app

hi, I had to recover my iMac (Sequoia OS). I Installed Norton 360. I cannot launch Norton application … have always popup message: “The application “Norton” is not open anymore.” Any idea?

Product & version number:

OS details: OS Sequoia 15.4.1

What is the error message you are seeing? The application “Norton” is not open anymore.

If you have any supporting screenshots, please add them:
