LG G4 Problem with "camera unfortunately stopped working"

Recently my camera on my LG G4 has been having some issues and is not working at all. When opening the camera app either front or rear there is just a black screen and after a moment the message "camera unfortunately stopped working" and the app is closed. Also I have checked that the flashlight is not working but that must be related to the camera problem I guess. It is not the first time it happens. Sometime ago I had the same problem for about two weeks but the problem magically solved itself. But know it reappeared when I tried to open the camera through the locked screen menu while having another camera app which might be unrelated but I am not an expert. I have tried several usual methods to solve the problem: - Rebooted the phone; - Deleted Cache (Both camera app and gallery); - Deleted App Data; - Tried a third party app; - Factory Reset; **Nothing Worked!** I have know tried to use adb and android studio to see what kind of errors are issued and what I got was this: --------- beginning of crash 02-03 22:31:11.147 3599-10463/?

I guess the interesting part of the log is this, but there are a lot of errors previously that can trigger failure. So I will post some of those since there are too many too fit them all here: 02-03 22:31:05.642 520-10471/? E/mm-camera-isp2:isp_module_start_session:178 session id 1 02-03 22:31:05.645 520-10472/?
