Problem "All your shields are turned off"

image

Good afternoon, I installed Avast Premium on my notebook and since then I have not been able to solve this problem, even if I click on TURN ON it does not solve it. Any tips?

When I click on VIEW ALL ISSUES this appears, the firewall cannot be activated either

I had a similar issue some time ago - on Avast Free - this is what I tried to resolve it.
