  Hi
  See what pivot error is:
  https://featips.com/2023/01/30/ansys-solver-pivot-warnings-what-are-they-and-waht-to-do-about-them/
  and the message you show as that explains the reason (material, constraints, etc.)
  Most likely shared topology related (som members are not connected). You can check which parts by doing a modal analysis and see for rigid body modes.
  
  See this video on how to do that (shared topology/connect parts):

  Also this shows how to do this properly:
