Impossibility of accessing to Avas Menu

Since Nov 1st Avast is theoretically running, I can not get up the menu. I have the icon, and If I use control+alt+sup to see the task (figure)
avast
This problem is in parallel with the impossibility of accessing to my work by VPN. I try to disconnect Avast, but I can not, and now I don’t know if the problem is the antivirus or the VPN work.

I am using windows 10 pro Nn and Avast antivirus by paid.

You are using two Antivirus programs side-by-side?

No, Avast is the unique anti-virus
