I have found a solution! I did multiple things:
Used newer template files for Android from Qt/6.2.3/android_arm64_v8a/src/android/templates/ (res/values/libs.xml - overwritten, build.gradle - overwritten, AndroidManifest.xml - copy and paste and then edited the content and added the missing things from my old one) Used newer gradle files from /Qt/6.2.3/android_arm64_v8a/src/3rdparty/gradle/gradle/wrapper/ - overwritten Upgrade of Qt Creator, Qt 6.2.2 -> 6.2.3, Android SDK, Android NDKMy current Manifest:
