Avast Icons On Desktop Are No Longer Functional

This is probably more of a glitch than a virus, but for some reason the icons for Avast cleanup and the anti-virus scan no longer work.
The only thing that is different is I got a free VPN service from Protonmail.
Thank you in advance for your help.

Tried avast repair and reboot ? >> https://support.avast.com/en-eu/article/Repair-Antivirus

They are working now. Thank you.
