Long running UWP application closes randomly with Exception code

[ElaJegen]

This is an UWP app that communicates to PLC controllers. It send commands, receive real-time data every second, display data with graphs and textfields.

Application was running for 19+ hours before a crash happened.
With Event Log, we were able to collect Exception codes:
Error codes:
1: c0000005 (Windows.UI.Xaml.dll)
2: c0000374 (ntdll.dll)

We were not able to reproduce this exceptions on our debug environment.
Don't have a steps to reproduce. Really appreciate any help!

Just an idea: It might be some issue related to app suspension. Try postponing your app suspension with extended execution.
https://learn.microsoft.com/en-us/windows/uwp/launch-resume/run-minimized-with-extended-execution

var newSession = new ExtendedExecutionSession();
newSession.Reason = ExtendedExecutionReason.Unspecified;
newSession.Description = "Description";
ExtendedExecutionResult result = await newSession.RequestExtensionAsync();

// Controller process

newSession.Dispose();
newSession = null;
