Apps crash at start on Android devices with API levels 23-27

Have tried to run example app build with 6.8.0 beta2 on Android emulator with
'system-images;android-23;google_apis;x86_64',
'system-images;android-24;google_apis;x86_64',
'system-images;android-26;google_apis;x86_64'
'system-images;android-27;default;x86_64'
also 'Nexus 5' physical device (with Android 6.0.1).
App crushes at start, output similar for all devices:

E AndroidRuntime: FATAL EXCEPTION: qtMainLoopThread
E AndroidRuntime: Process: org.qtproject.example, PID: 5496
E AndroidRuntime: java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "getentropy" referenced by "/data/app/org.qtproject.example-1/lib/arm/libQt6Core_armeabi-v7a.so"...

There are no such crashes with Qt 6,7,2 (with same JDK 17, NDK r26b). Is it Qt 6.8 bug or there are known changes in Qt 6.8 which breaks compatibility?
