Forgive my asking, but I noticed the like for my comment so I'm assuming that what I outlined is what you tried, taking permission away from all other apps. Safe Mode would essentially be the same thing, but it might be worth testing the camera in this mode if you haven't.
What about clearing the cache and data for your camera app? Settings>Apps>Camera>clear cache, data and force stop the app.
After those two I'd probably clear the partition cache. A little more involved but no ill side effects. To clear the partition cache this link should guide you...

If those three fail a factory reset would be a last resort.
