Hi Alex,

We are on QBES 22.00

This problem not only happen in one devices. It happened to all 4 devices running:

Windows Server 2016 

Windows 10

We have tried all the mentioned method. Uninstalling and Reinstalling. And this is nothing to do with company file and network issues. 

I expect a more concrete solutions not a standard remedy. We have been using QBES since 2009 so we know many trick and tips on this software.
