Icon Files can not show

They are in Directory Opus, are normal ico.[Big Icon mode]

They are in Windows Explorer, are image [Big Icon mode]

The two screenshots seem to be showing different files?

Please zip and attach one of the icons that doesn’t display.

Windwos Explorer [Big icon mode]

Directory Opus [Big icon mode]

Directory Opus [Thumbnail mode]

The non-display of icon files is not an isolated phenomenon; all icon files are not being displayed.

If it affects all icons then it probably means Preferences / File Display Columns / Icons / Show generic icons for... has been turned on, and needs turning off again.

Otherwise, please zip and attach some example icons with the problem.

I've turned that option off. But it still doesn't show.

I suspect it's the operating system
