Here is how to add Sync as an exception:

1. Click on Start and type control panel on the search bar then click on the search result showing Control Panel Desktop app
    
   

 

2. On the Control Panel window, click on View by: and select Small Icons (if it has not yet been set that way) then go to Windows Defender Firewall

   or

   C:\Program Files (x86)\Sync\sync-taskbar.exe
