Game stops responding - No solution?

I have had a few complaints about the program I released, made in unity about 3 months back , because it stops responding for no apparent reason. The time between crashes seems to vary and is not do to any specific actions within the program (game) seemingly. I have not encountered the problem myself on the 3 systems that I own (all windows 7, 2 PC 1 Laptop) however I can provide an output_log sent to me by one of the users who bought my program. This seems to be a unique case between 2 users, no one else has encountered this problem. One user in particular has run the game on 2 systems (1 laptop, 1 desktop, both windows 10) and only experiences the issue on the Desktop (Windows 10).

My question would be: Is this a Unity problem or a Windows error? How can I solve this and possibly prevent it in the future??

The Log attached has several instances of ERROR: SymGetSymFromAddr64, GetLastError: ‘Attempt to access invalid address.’

Does anyone have any idea what this could be? This is the last resort since i could not find a solution by simply Googling like any other issue I’ve had.
