System Information
Operating system: Linux-6.5.0-44-generic-x86_64-with-glibc2.35 64 Bits, X11 UI
Graphics card: NVIDIA GeForce RTX 2060/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 535.183.01

Blender Version
Broken: version: 4.3.0 Alpha, branch: main (modified), commit date: 2024-07-25 09:06, hash: b76603b6bf72
Worked: (newest version of Blender that worked as expected)

Short description of error
Blender crashes when opening a blend file that loads baked data containing instances that hold empty collections.
Another way to phrase this would be: "Blender crashes while loading corrupted baked data, which was caused by baking empty collections as instances."

I've attached two blend files: one is a pre-bake file, and the other is a baked file with the baked data.
Blender crashes around 70% of the time when opening the 'Crash' blend file. If it doesn't crash, try scrubbing one of the node sockets to refresh the UI.

Exact steps for others to reproduce the error
Open the 'PreCrash' blend file
Bake the geometry node tree
Change any node property

Hi, it seems you're using build provided by distro package? Does it fail in official 4.3 buildbot build?: https://builder.blender.org/download/daily/

It's also crashing in the non-modified version, I modify blender to debug better the .instance_reference attribute.
Here is a video with the PreCrash blend file:

Be aware that you have to download the baked data (.json, .blon) and put them in the right path, otherwise, blender won't try to load the corrupted data.
