ADB0000 error: Why doesn't my Xamarin.Android project deploy anymore?

Issue

I used to be able to deploy my Xamarin.Android project to devices but for some reason I can't anymore. I can still successfully deploy UWP and iOS.

I get the error:

ADB0000: Could not determine the installation path for package com.my_pro.proj. `adb shell pm path com.my_pro.proj` returned ''.

Solution

Running adb shell pm uninstall com.my_pro.proj via the command prompt is the only thing that works for me whenever I have this error.

My hypothesis is that this error happens when the app gets installed for one user of the device manually but not for all users of it.
