Passthrough activates on Unity App on Resume from Stand-By

So I've build an app using Unity and the SDK provided by Meta on Unity Asset Store. The verison is the 2022.3.44f1 and the application works on Quest 2 and Quest 3 devices.

The problem is that when the devices go in Stand-By mode and then they "Wake up" again, the application starts to flicker showing the reality with the passthrough and the application in a very fast and flashing way.

The only way to stop this is to press the Power Button and make them go sleep again and then retry waking them up hoping that the problem is gone, sometimes it works at first attempt other times it needs more times.

Is there somethign that I can do?

This last part is interesting:

I'm also posting a video recorded with the phone through the lens because when I tried to use the recording program of the Quest, this was properly recording the applicazion while the flickering was happening, so the passthrough was not visible in the recording. This let's me think that the problem doesn't come from the Unity application or other settings that I should do...
