#650 Can't start 6.x app, but 5.x works. Crashes with PipeException / EndpointNotFoundException

[mach]

Behavior
Main window displays, but then a second later crashes with the standard dialog "NAPS2 (Not Another PDF Scanner 2) has stopped working".

Version Information
Tried a couple 6.x releases, including latest 6.1.2, which does not work.
5.8.2 works great.

Application event log shows:

Application: NAPS2.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.

Exception Info: System.ServiceModel.EndpointNotFoundException

Some texts are in Slovak language, but if necessary, I'll translate them.
All are just generic event log texts, so its "readable" by context.

The 5.8.2 works just fine on the particular system.

[SelfMan]

Its a Windows 7 Pro x86 system (all updates applied) with ESET NOD32 Antivirus.
When I ran NAPS2 as a different user, the application started just fine. It just had no config files.
So I've tried to remove the config files from %APPDATA% of the primary user, but it had no effect.
This system has a Samsung SCX-3400 Series Multi functional Printe which is connected via USB,
It looks like NAPS2 is doing some evals of the user settings after the startup and failes here.

And I had no antivirus installed other than Defender.
I am unsure if @selfman 's issue is the same as mine or not.

In my case, the following error was in AppData\Roaming\NAPS2\errorlog.txt which I had not checked months ago:

2019-12-31 20:28:09.4762 An error occurred that caused the worker application to close.

So I looked at C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\machine.config and found IIRC 2 references to Microsoft.VisualStudio.Diagnostics.ServiceModelSink.Behavior. The last modified date for this file was years old. Further, these 2 references were not present in machine.config.default, so I restored the default configuration, and NAPS launches fine now. I wonder if these references were still in there from a previous Visual Studio install that was uninstalled years ago?
