I developed an UWP app with Cordova and IndexedDB storage. I need recover some information stored in the indexed database adding a new action to source code.
I got access to the app path at C:/Program Files/WindowsApps/com.mi.app_xxxxx/ inside the www directory I added the new action code. When I start the app it crashes without error messages.
You may not manually tamper with the files in the app install location (C:/Program Files/WindowsApps/ folder). This is a security measure and if any app file is changed in this folder, the system will not allow the app to be launched. The reason for this is that otherwise, anyone could access your app and for example replace some library with malicious executable or crack a licensed app.
