Hello Support,
I too am having the same problem with not being able to open Enpass from the Windows Store. I've uninstalled it twice with no luck as the app doesn't respond, so I have to close it. This seems to be happening after a security update to Windows. I am on Win10 Pro Version 20H2 (OS Build 19042.685).
The version of Enpass from the Windows Store is: 6.5.2.0
Below is the Application Log with Error and Event ID 1002 each time Enpass doesn't open to where I have to force a close of the program:
The program Enpass.exe version 6.5.2.0 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Security and Maintenance control panel.
