As Fugi said, try another file
There are times when a file becomes corrupt
Also, if there is a ship gun, some ground guns are involved in muzzle flash closeup it could crash.
I had a film just to get siren sound, it will only crash, it will never open
SO, I’m starting to lean towards some crashes COULD be associated with certain sounds. I have no proven conclusion, but a pattern is forming on my end
This is why close up ship or field guns are not in my videos.
