CivilConnection stops when xml export starts

Hi, I am using Civil Connection with Civil 3D 2020 and Revit 2020. I have installed Civil Python, Python command worked in Civil 3D, Dynamo from Revit 2020 shows the active civil 3d document, its corridor and codes, removed the Read only from CivilPython.dll file, Still when it comes to shapes it stops working. I have checked all posts and everything is in place. What I observed is that when exporting any xml it stops working. Script and temp file images added.
