Latest version of Qt/QtCreator does not sign apk silently

I'm migrating from Qt 6.2.2 (QtCreator 6.0.2) to Qt 6.9.0 (QtCreator 16.0.0).

With Qt 6.2.2, I could simply compile and deploy an apk on an Android device. The project's properties has a "Build Android APK"/"Application signature", but I never used it and everything works fine.

With Qt 6.9.0, if I don't check "Sign package" in "Build Android APK"/"Application signature", I get the error:

adb: failed to install C:/Users/XXXXXXX/Documents/QtExample/camera/build/Android_Qt_6_9_0_Clang_armeabi_v7a-Release/android-build//build/outputs/apk/release/android-build-release-unsigned.apk: Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES: Failed to collect certificates from /data/app/vmdl639520454.tmp/base.apk: Attempt to get length of null array]

The only way to have the apk be deployed is to create/specify an keystore, and unlock it with a password. And this has to be done every time the project is being loaded, which is very annoying.

Any workaround letting me deploy the app without having to use a keystore nor enter a password would be really appreciated.

Edit: This problem is only for Release apk, Debug apk are silently signed. But one may want to use and test Release apk during development too.
