[UWP][C#] Random crashes - Faulting module path: C:\Windows\System32\Windows.UI.Xaml.dll RRS feed

  • Question

  • I have an app written in UWP/C# running on Win 10 tablets - OS is Windows 10 Pro v1809 build 17763.

    I've read a lot about this crash but the posts are usually not about random crashes. 

    What can I look at to fix this issue?

    This is what is written to the activity log for the crash.

  • Hi Paula M,

    Your above information was not enough to help you diagnose this issue. Please provide a minimal reproducible code sample for more diagnosis.

    Besides, the latest windows 10 version is 1903. If possible, please try to test it on the latest windows 10 OS.
