Unable to instantiate applicati

Answer 1

No need to disable "instant run".
1. go to project's root using File Explorer
2. Finish Android Studio(AS)
3. delete(relocate somewhere) ".gradle" 's folder content
(to clean some cashs and old artifacts)
4. in res folder clean off all inappropriate files
5. launch the AS again
6. in module's build.gradle set "buildTypes { debug {minifyEnabled true" to false
(that looks like an error was in my proguard file, kek)

Sync, compile and run the app again :/
