Any solutions will be helpfull.

Answer 1

The issue is that the type de.blinkt.openvpn.core.NativeUtils is defined twice in the included dependencies. R8 compilation ( minifyEnabled true ) does not allow multiple definitions of the same class. You will have to analyze your dependencies to see how to avoid that. The error message contains the location of the two dependencies.
