I understand that using RoadRunner version 2020a Update 3, you are receiving the error "> WARNING: Multiple triangles detected in polygon walk. Vertical gaps may be present in final triangulation."

The warning you are seeing relates to minor geometry/triangulation issues in the scene and can be safely ignored. If you continue to have issues, you could try switching to using all default settings.

If you are experiencing crashing that accompanies the warning, that may be a separate issue.
