Release build gives me: Unfortunately, “App” has stopped

See original GitHub issue

Issue details

After August 1 2019, I developed “Happy Can 15.0” with 64-bit ABI support: https://play.google.com/store/apps/details?id=com.happycenter.happycan.android To do this, I updated LibGDX, Gradle, Android Studio etc. And for the first time, the release build does not run on some devices such as Samsung SM-T113 Tablet and some of Android 4.x devices.

It throws that error message: “Unfortunately Happy Can has stopped”

My game is running in debug mode on all devices but it is not running in release mode on some devices: https://imgbbb.com/images/2019/10/03/1d59bb91a6472369d.png https://imgbbb.com/images/2019/10/03/2b64b0db1c38003ca.png
