Auto-Protect not working?

For 3 days my Norton is giving me a red error when I open it. It says 'you are in danger, your pc is not automaticly protected vs virusses, spyware and other risks'.

When I press the yellowish button: Solve now, Norton seems to be trying to repair the auto-protect function, but it always fails.

When I look into my settings, I can see the slider of auto-protect greyed out (but it's on, I think). All the rest is working perfectly fine!

Running windows 10.
