Prompt [Q] HTC One (m7) rooted & custom rom installed but camera

Hello i have successfully rooted my phone, and installed android-4-4-kitkat-rom-root-for-htc-one using TWRP.

Everything is fine, the rom running like a charm, but my camera does not work.
I have successfully installed Google Apps

I've also tried to install new version of camera software, but there is a conflict, and i don't know how to remove the google apps camera.
I tried to install "A better camera" from android market, the app is installed but i received message - can't start the camera.

So the problem is in the Android, not in software i think.
Can somebody help me? I can provide specific information about version of software.

Thanks
