Avast SecureLine VPN window stuck in minimized size and cannot be resized

Hello,
I’m experiencing an issue with Avast SecureLine VPN on my Windows system. After installation, the application window remains stuck in a tiny, minimized size and cannot be resized, maximized, or properly restored. I have already tried:
Reinstalling the application
Resetting the window position via system context menu
Cleaning related registry entries

Unfortunately, the problem persists.
Could you please assist me in resolving this issue or provide instructions for fully resetting the application’s window layout and settings?
Thank you in advance!

Did you fix it? I called Avast, and after wasting one hour, they couldn’t solve it.
