APK cannot install

Question

Our application is used to working. The last update was published 2 and a half weeks ago when the apk file was created and worked correctly.

The last 2 days, when we try to create an apk (signature or not a problem), no errors are sent from Android Studio, but when the apk is installed on the phone, the application will not be able to install with the error "Application not installed"

In addition, the following errors appear in Android Monitor.

Class not found when unmarshalling: com.android.packageinstaller.InstallFlowAnalytics
