After the last update it does not work anymore.

It seems that WhatsApp Desktop for Windows is now only available through the Windows App Store.
Version 2.2242.6.0

Accordingly, the installation path will be different.
The path for apps is:
C:\Programs\WindowsApps

Probably that is the reason because it no longer works
