  • There is not enough information here to diagnose this. Can you try attaching the windbg debugger to the running app to see if it provides better crash information? – Stefan Wick MSFT Feb 05 '19 at 14:37
  • [use in Device Portal](https://learn.microsoft.com/en-us/windows/uwp/debug-test-perf/device-portal) the Crash data entry, select your sideloaded app and configure it to create a dump. analyze the [dump with windbg](https://stackoverflow.com/a/28437625/1466046) – magicandre1981 Feb 05 '19 at 15:01
  • Extracted crash log from microsoft store pfa in the below link. [link](https://www.dropbox.com/s/ex7j3unc1y77zmm/stackTrace.tsv?dl=0) – Harish Kinthali Feb 07 '19 at 11:09
  • again, do what I said, create a crash dump and analyze the dmp with windbg – magicandre1981 Feb 07 '19 at 15:48
  • The .tsv file doesn't contain enough information. What you want is the actual dump file (.dmp). Easy to create if you can reproduce the crash with windbg attached (or via Device Portal as suggested in other comments). – Stefan Wick MSFT Feb 08 '19 at 22:55

@Harish,

Does any of your Xaml markup include the following setting?

FocusVisualPrimaryBrush="{x:Null}"

or perhaps any of the other FocusVisual properties being set to null like

FocusVisualSecondaryBrush="{x:Null}"

We were getting a very similar error message and observing a similar crashing behavior with our UWP application as mentioned in this post.

And that Null setting was the culprit in our case.
