You can try deleting them and test to see if it works. Add one back at a time until you find the one causing the problem. The other issue could be memory. It may be too low to allow the camera to function. Check device status. Remember Apps use internal memory not the SD card.
Do you have any idea how much free ram need to start the camera?
