Cannot start XnView Classic on Windows10 PC

[gorby5775]

Hi XnView Classic Support Team,

XnView Classic for Windows has been working on my Windows 10 PC for about a year, but it suddenly stopped launching.
It starts for a split second, then closes within 0.2 seconds.
Even after uninstalling the current version and installing the latest XnView Classic 2.52.5 for Windows, the issue remains unchanged.
What could be the cause?

Cheers
