Unhandled Exception in Microsoft Store

[warrenronsiek]

When I run my react-native-windows app via sideloading from the generated _Test directory, everything works fine (in 4 different windows environments). If I take the same .msixupload package and submit it to the microsoft store, the app crashes on launch with the following error and no other logs:

Application Error:

I made these builds via store submit workflow in VisualStudio. My RNW version is 0.74.8.

From what I can tell based on the video they gave me, the app doesn't get past the loading screen. I've added exception handlers for "Unhandled Exceptions" that might happen, but they don't trigger, which indicates to me that the app doesn't even get past the instantiation. I've looked through the docs/github, and the closest I can find is the issue #4749, which seems like the same problem but it also seems to be fixed.

Two questions:

1. Any Idea what might be going on here?
2. Given that the side-loading works, I'm at a loss for how to replicate the issue. Any ideas on how I might go about doing this?

Good news, I've been able to replicate the issue by installing via unzipping the .misxupload double-click-installing the .msix on windows11. Still no clue whats happening as the issue doesn't leave any .NET runtime logs:

Application: ChronoKeep.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: exception code e06d7363, exception address 00007FF896A7F39C

Ok looks like this is a generic UWP problem and not necessarily related to react-native-windows: https://developercommunity.visualstudio.com/t/UWP-App-crashes-during-start-when-compil/1304475?ftype=problem

Although, given that I'm building it via react-native run-windows <args>, arguably something could be changed in RNW to avoid this. Investigating...

Replicated the issue using a vanilla RNW application. Closing the discussion and opening a bug.
