Failure log from Dev Center

Question

Recently I’ve release my Windows 10 UWP application in store . Last week I released a new update in store ,after a week I receive lots of mail from users about a bug in my app.(Pages that want to connect to database can't open and they crash)

Funny part is that when I deploy and run it by visual studio or Powershell (appx-package command) everything works fine, so I can't find a thing.(Even in RemoteMachine and Emulator)

So I was checking my dashboard in dev center and find some "failed log" there.

How can I use these logs to find my problem?

I'm really stuck and don't know what to do!!

Answer 1

Solution:

In Properties of the Project there is a file named Default.rd.xml that contains an element like <Assembly Name="*Application" ...

So by mistake the attribute it was changed to name="*Application" (Don't know what changed that and VisualStudio didn't notice that.)
