Avast Premium Security not opening up

Hi guys. Just got home, turned on my PC and went to do a light scan of my computer but my Avast won’t open when I click the icon. Anyone else having trouble? Never had this happen before; I’ve rebooted - I still have 10 days on my subscription; no other issues. Windows 10 Home here and up to date. Any ideas on what I could try? Thanks !
