CGAL error: precondition violation #6

When running locally, I encountered the following error, which is mainly due to an error in the intersect(A, B) function of PolygonMeshProcessing when operating on a potentially non-standard triangular mesh A. This is because the 3D extruded model constructed with extrude() during the construction of the Visual Hull is not entirely standard, leading to the error.

Extract Visual Hull for carving [Running] [5.00%]:CGAL error: precondition violation! Expression : is_triangle_mesh(tm1) File : E:\CGAL-5.5.2\include\CGAL\Polygon_mesh_processing\internal\Corefinement\intersection_impl.h Line : 1677 Explanation: Refer to the bug-reporting instructions at https://www.cgal.org/bug_report.html

I would like to get more information about the error. Could you paste a snapshot of the problematic mesh before or after running extrude()？A wireframe or so is OK.
