Pointools point cloud export issue

Hi,

When I tred to export point cloud to .pod file from pointools, this dialog appear, and all of the point cloud will disappear?

I tried to export .pts and .xyz, this will not happen.

The size of the point cloud attached in pointools is small, 10 Mb.

And the software version information is here:

Please tell me how to solve this issue, thanks!
