Thanks for posting the screenshots of 6DOF properties. I did not see any problem with them. In the meantime, could you please also add a few screenshots for dynamic zones, especially the rigid bodies?
Sometimes bad initial conditions or mesh quality could also lead to failures of dynamic mesh (DM). Can you also please try to get a steady solution by turning off DM and then turn on DM? If the error does not occur again, you might need to give better initial conditions or improve the mesh quality. Let me know how it works.
