Just to cover all the bases, is it any png file, or is it just one specifically? Can other programs read the png file correctly?
Also, considering you're on ryzen, are you on the latest (stable) bios for your motherboard?
Past that, this would be outside of my knowledge for the cause. It appears to be an nvidia-related issue based on nvwgf2umx.dll, but as always with crashes, this could be a red herring.
