Enpass V6 Crashes on startup (Windows 10, Store and Tradidional Win32)

[Bert]

Hi, Enpass won't start anymore since the V6 update from the Windows Store. It briefly shows the startup screen (without contents), then crashes. The crash-reporter shows up. Same goes for the traditional Win32 setup. 

When I go back the the previous version (5.6.19) System Restore, the old app works fine.

I'm using Win 10 Pro (1809) on an HP Envy laptop, I7-8550, 16 Gb Ram, Windows Defender as AV, Hyper-V, Developer mode etc. disabled. 

On another latop, also Win 109 Pro (1809) everything works fine, same on our iPhones.

 

Please help!
