Please See my Latest Update
On the 22nd of June 2018, Microsoft informed me that my UWP App with a Win 32 backend cannot be tested due to it crashing at startup. After contacting the app certification team, they said it has been tested on two Windows 10S devices of which none successfully launches the app...
They suggested I contact support but I cannot dash out R1000 for a support engineer to help me change one or two things...
I unfortunately do not have any logs to post or any furtherer details... What I don't get is that the app passes the WACK with flying colours, absolutely no errors. It also works perfectly on three Windows 10 Home Editions.
Please note that I built the app from the ground up. No Project Centennial or any conversions.
Has anybody encountered something similar? Have I missed some thread on the internet? Please help.
Thank you.
Edit
The app has a UWP UI and calls LaunchFullTrustProcessForCurrentAppAsync() upon the GridLoad event of the UWP app to display NotifyIcons.
If any more information is required, please ask.
Edit
Could a Debug.WriteLine call (I forgot to remove it before packaging and submitting) or any of these namespaces cause an issue?

Sorry guys, I've never worked with Windows 10S before.
Edit I asked Microsoft to only test it on Win 10 Home, etc. and they let me know that, even under 'normal' conditions, it crashes. I still do not have any logs. However, on my side it works on 3 Win 10 Home devices without issues.?

Well, it has been an interesting 9 months...
Since this thread's last update, I have discovered how to deploy my app through the MS Store to certain people only. Great, I could then debug. When installing and running it through the Store, it crashed on the splash screen as MS reported. I could get reports through Event Viewer. Think it was MoAppHang and some .Net Exception (please read on before commenting)
Late last year (about October, sorry can't remember the exact date), I had to delete my user profile as it was corrupted. I then randomly repackaged the app, and uploaded it. It surprisingly worked on my test devices. So, I uploaded it for certification and it passed. All was well.
Fast forward to now. I need to update it. Actually, I have written the code and packaged it. Now I upload it using a package flight to the test devices. Behold, the invisible bug is back...
Please see Event Viewer reports and Visual Studio debugging screenshots on this OneDrive link . Please note, the files under Event Viewer do not correlate to the Visual Studio debugging run. Do these get stored somewhere else in Event Viewer? I also could not get a .wer file for the debugging session. You should be able to follow the debugging session according to the screenshots modify times.
What I did was open the solution with the source code in VS2019, but went to Debug -> Other Debug Targets -> Debug Installed App Package. I checked Stop at first statement (does this relate to the first statement in MY code? If it does, it is not my code that's buggy as it does not reach my code, or I am misunderstanding this function). Could this be a bug in the CLR? I have no C++ interop directly in my code. I have also included the debug log.
One thing to note is that I have changed my environment. I installed a new SSD and the May update of Win10. I have also changed my min version from 15063 to 16299 and my target to 18362. Could it be looking for some file that is present during launching (and debugging) from Visual Studio as well as Sideloading, but not when launching from the Store?
Compile with .NET Native tool chain is checked. Before I ran it from Visual Studio for the first time, I did delete the bin and obj folders. Can it have something to do with Optimize Code being checked?
One weird thing is that this app (Caps, Num + Scroll Lock Checker (Pro)) is somehow linked through the MainPackageIdentityName in the Package.StoreAssociation.xml to one of my other apps which is in development, but not at all publicly released; though, I have reserved the new app's name so long. Could this be a Dashboard related issue?
Any advice would be appreciated.
