Quest 2 Meta cams not working properly

Hey, my Meta cams (so the cams used to see the environment etc.) doesnt really work. So if I start my Quest 2 and it asks for the Guardian thing to set up it does work and I can see my real surroundings through the cams but it only works for like 3-5 seconds until the cams crash? Basically they freeze and it stops working for some reason. But also when I start the Quest 2 I already have a black screen for the setup and basically have to do the guardian thing "blind". I already did a Factory reset but that didnt fix the issue.
