Error reported when add joint to a prim with reference

After I added rigid body and collision preset and joint to a prim with reference ,some errors were reported.
Is there any way enables me to remove reference for these prim?


something failed, not sure from the picture what though exactly. Most likely a shape failed to be created.
You can remove the instancing to remove the “grayed” out reference. On the reference prim uncheck the isntancable flag.
Feel free to share with me the USD asset I can take a look what the problem might be, curious what it is. I did not see this error yet.

Thanks ,problems are solved. It is actually because of instancable flag.
