As many have already posted on similar problem, when opening Avast from desktop icon or via start menu all we get is a blank white box.
If We right click on the tray icon we can access the subscription information, troubleshooting and componets menu but this dosent allow access to the scanning options usually shown on the main user interface.
Have uninstalled/reinstalled Avast multiple times and also followed the instructions to clean install but still have this problem.
OS is Windows 10 and avast version is Anti-Virus fre version 18.6.2349.
