Crashing for no reason now

I geo tagged three images without incident, I select the fourth image and it crashes relentlessly now. I even tried the geo tagging images that it had no problem with moments earlier and they cause it to crash upon selecting them. Tried restarting my iPhone 6, then deleted and reinstalled the program, but nothing works now. So random for it to do this in mid job.
