Blender Version
Broken: version: 2.93.0 Alpha, branch: master, commit date: 2021-03-01 01:00, hash: 1638af109e
Worked: (newest version of Blender that worked as expected)

Short description of error
I have two object. There are in RigidBody collection. One First Cube - object with "Point instance" node in geometry nodes. Second - Icosphere that i place as instance object in "Point instance" node of Cube. When i dublicate Cube (Shift + D) - blender crash.crash.blend

This should be fixed by D10577. The crash is unrelated to the dependency cycle warnings.
