Here is the logo screen I am talking about: Stuck at logo screen, and closes itself after a while. If app launch successfully, repeat step 3.

Open the app through Start Menu, and let the app run for at least 10 minutesĬlose the app, and try to launch it gain. Install the app through Visual Studio 19 or sideload build SDK: Microsoft.WindowsAppSDK (1.0.0-experimental1) or Microsoft.UI.Xaml (2.8.0-prerelease.210927001)Ĭreate UWP with WebView2 package through WinUI3 or WinUI2 If I installed through sideload build, I won't be able to reinstall with the installation wizard. If I installed through visual studio, I won't be able to launch with visual studio. I have tried to uninstall the app with command line Remove-AppxPackage, the process is initialized but stuck initialized. There isn't any error log shown in the Event Viewer. I also tried installed through VS studio, sideload installation, debug build and release build. I have tried to import WebView2 into a UWP app with WinUI2 and WinUI3. The app I have written only has a WebView2 control. The only way for this behavior to not show up is to always run the app through visual studio debugger session. However, after the third or forth time, the app will always stuck at the logo screen and I won't be able to launch or uninstall it until I have restarted my computer.

Sometimes, after the first or second times this behavior has shown up, I can still close the app while it stuck, then try to launch it again and it will launch properly. There isn't any process running in the background, and there isn't any error prompted. In term of app lifecycle, I don't think the app is started at all. If I open a UWP app for about 10 minutes, after I close the app, I won't be able to open it again.
