No signal and camera doesn't work. Uploaded the logs

Hi, I have nexus 5 stock ROM 5.1.1.
After some hours of being on my phone lost mobile reception until I rebooted.
In a different case no app could access the camera.
I've attached the logs from CatLog for the both cases.
I would be very glad if someone could give me at least some direction on how to solve these issues.
