Installation failed when two applications are installed (Android Play Store)

We have developed two applications for the same client, both have some plugins in common (eg QR cordova-plugin-camera, cordova-plugin-file, phonegap-plugin-barcodescanner). Both are successfully compiled and published in the Android Play Store. When installing from the Store separately, they are installed without any problem, the problem comes when you try to install the second one (regardless of the order), an error message “This application cannot be installed” appears from the play store. In Apple store there is no problem.

Both apk have a different ID. The points indicated in the troubleshooting have been made, the project files have been completely cleaned, the Android Studio cache was cleaned, the AndroidManifest.xml file was completely reviewed but the problem persists.

Please help, we have a very angry customer waiting for an answer.
