MicroStation Connect Crashing issue with TSCAN contour preview

MicroStation crashes when I run TSCAN contour with preview setting.  What preview does reflects right away the changes I make in lidar points selected as surface.  I had no issue running TSCAN running contours preview/display setting with MicroStation V8i which is no longer supported or available option for me.

Is there setting I can trigger to run the program without crashing the software? Or has anyone have similar challenges as I using TSCAN on MicroStation Connect?
