Visual Studio 2019 - Xamarin.Forms - Unable to debug or release on Android 10 phone

Marcel Delhaye 26 Reputation points

I am developing a Xamarin.Forms application for Android. For a few days (actually, since installing my app from Google Play), I can no longer debug my program on a Galaxy Note 10+ with Android 10.
When I run debugging, after copying the files, I get the following message:
Looks like the package com.ApriSoft.memocourses is already installed, trying to uninstall it first…
The message is still displayed, and nothing happens.
However, I manually uninstalled the program from the phone, even removed Mono shared runtime, as suggested in some forums.
What's also strange is that after uninstalling the program from Google Play, the reinstallation is done without downloading any files, and the data is retained.
Please help me, I am stuck in the development of my program because I can no longer create a release to generate an APK. Thank you very much
