Robotiq 2F85 Gripper Model Falls Apart When Running Simulation in Isaac Sim 5.0

[chandlerye]

1. Environment Information：Isaac Sim Version: 5.0.0
2. Problem Description：
   After importing the Robotiq 2F85 gripper model into Isaac Sim, the model displays completely in the Stage view (base, fingers, joints, and other components are properly positioned). However, when clicking "Play" to start the simulation, the model immediately "falls apart"

I hope the official team can help identify the root cause of the model falling apart (e.g., ineffective joint constraints, abnormal rigid body mass configuration, lost constraint information during import, etc.) and provide targeted solutions or compatible configuration suggestions.
