Preview shown, later crashes XYplorer

[MIRKOSOFT]

Hi!

I have problem with one preview.
Preview is from Windows Explorer extension to display content of Commodore disk images.
Preview is shown, but later - near 30 seconds - it freezes XYplorer and then is not responding, it reports crash or I must to force closing.
Here is preview with handler ID:

Where can be problem?

Thank you for all.
