RGB Camera does not work on OnePlus 9 5G [Solved: Power Saving Mode Nebula]

I am currently working on an app, that should read a QR Code and then make an API Call with a key from the QR Code. This app works just fine on the NREAL Computing Unit from the Dev Kit. Today I tried on an OnePlus 9 5G. The RawImage, which normally displays the RGB Camera from the NREAL Light, stays completely white and the QR Reading does not seem to work. Doas anyone have a clue, why the RGB Camera does not seem to work with the smartphone?

Issue is solved. It was the power saving mode of Nebula.
