Android applications fail to launch

https://bugreports.qt.io/browse/QTBUG-78440

This issue still continuous on qt opensource 5.14 stable version. After opened my android apk, i take this error.

_{qt.qpa.plugin: Could not load the Qt platform plugin "android" in "" even though it was found.}

_{This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.}

_{Available platform plugins are: android.}

I used ndk 21rc, 20, 15, 10e(not worked) and android sdk 29, 25, 24, 22 but it didn't change anything. Still getting the same error.

In attachment, i will send my error reports after running my apk. (Tekniker)

I want to upload my project but it is really big, but i can say that, I can build and run on Windows 8-10, MacOS Catalina desktop and ios simulator, but i can't run on android simulator or android environments(phone(android 7.0) and tablet(android 6.0))
