Could you provide some more context?
Are you running a packaged build? Or deploying from Visual Studio?
Try taking a look at the log found here: C:\Users%username%\AppData\Local\Packages%AppID%\LocalState%project name%\Saved\Logs%project name.log%
There’s also a tool called DebugView made by Microsoft (https://download.sysinternals.com/files/DebugView.zip) which captures all logging in Windows into a log. Try running the application with this open and see if you catch any interesting logs.
