Short description of error
Hi, I am the creator of one addon for break all kinds of objects in Blender (easily).
I am having problems with the following known issue or bug when rendering my scene:

find_node_operation: Failed for (RIGIDBODY_REBUILD, '')
--------------------------------------------------------------------
Failed to add relation "Rigid Body Rebuild -> Point Cache Reset"
Could not find op_from: OperationKey(type: TRANSFORM, component name: '', operation code: RIGIDBODY_REBUILD)

etc...

This is a problem because when you have complex fractures you have a lot of chunks that are objects, maybe 1500 or more objects, and the rendering does not start until the Trace stops showing the error message. Some complex scenes become impossible to render with this problem. Baking the sim does not resolve this.

This seems to be caused by the fact that if we have a pointer property on scenes of type collection, once these are set to a collection that actually contains a rigidbody, we are getting the mentioned depsgraph failures.

Exact steps to reproduce

repro.blend

open .blend
F12 render (check console output to see all is fine without depsgraph failures)
run the simple script
F12 render again (check console output to see the depsgraph failures)

I think you'll have to share the code that makes this fail (in a way that is easily reproducable by devs).

Can you share a blend file including the code and/or a minimal Addon that exposes this?

Also does this still occur if you bake the sim? Scene > Ridgid Body World > Cache > Bake?

Yes, I will work on a simple script to be able to share it. I will upload it as soon as I have it.

yes, even if it is baked the message is still displayed.

Can confirm, only finding I have so far is that you dont even have to click the Add Collection button, it is enough to just choose a collection in the target_collections dropdown (namely either RigidBodyWorld , Zebus or Cube_low -- whereas Camera, Collection or Zebus_Originals seem to be fine)

OK, I got a very simple repro case now.
