Robot Assembler does not work for UR5e and Robotiq 2F 85

Omniverse Isaac Sim

Hello everyone,

I am currently trying to attach a Robotiq 2F 85 gripper to a UR5e. I followed this tutorial: Assembling Robots And Rigid Bodies and used the USD files provided in Create → Isaac.

First, I got the error “Cannot move/rename ancestral prim /Robotiq_2F_85”. To solve this, I saved the file flattened, reopened it, and tried again following the tutorial.

This way, it seemed to work, but if I move the robot slightly or close the gripper, the gripper detaches and flies away.
In the console i the the warning " Invalid PhysX transform detected for…" for all UR5 links and Robotiq parts.

I am using Isaac Sim 4.0.
I really do not know how to fix this since I am pretty new to Isaac.

Thank you for any help!
