System Information
Operating system: Windows-10-10.0.19045-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 516.94

Blender Version
Broken: version: 3.5.1, branch: blender-v3.5-release, commit date: 2023-04-24 18:11, hash: e1ccd9d4a1d3
Worked: (newest version of Blender that worked as expected)
I have not been able to reproduce this exact same crash with those specific files in 3.6 or Master, but I did get the same crashes with more complex drivers in Master, though not as reproductible, hence why I am reporting this bug for 3.5.1.

Short description of error
After importing a specific asset collection from the asset browser as Linked, once the library override is made on Selected and Content, duplicating this collection, then undo, then re-duplicating the collection will crash Blender.

Exact steps for others to reproduce the error
The blender file provided is to be used in an asset library. To reproduce the crash :
In a new file, drag and drop this collection asset in the scene, be sure to uncheck "Instance collection".
On the asset collection in the outliner, right click and Library override -> Make -> Selected and Content.
Duplicate the collection (right click in outliner).
Undo
Duplicate the collection over again -> Crash.

I started investigating this crash after I had a hard time working with multiple asset collections based on a fairly complex camera/light rig. I have narrowed down the culprit to be drivers within the shader node. If I delete the drivers in the shader node, I don't get the crash anymore. I have simplified my rig to the bare minimum to be able to share it and as long as I have a driver in the shader node of an object, related to another object I get this crash.

This particular asset file seems to be working fine in 3.6 and 4.0 so far. But I do get some intermittent crashes when working with the aforementionned camera/light rig (mainly when Library overrinding, but not always...). I have not been able to narrow down what causes those crashes, and unfortunately I would rather not share the rig publicaly as it is the property of my employer.
I hope this can help.

Thanks in advance
