System Information
Operating system: Windows-10-10.0.22631-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3090/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 551.23

Blender Version
Broken: version: 4.2.0 Beta, branch: blender-v4.2-release, commit date: 2024-06-29 15:08, hash: 53cb73ecead0
Also crashes on 4.1.1, which is the version that the file was being worked on.

Probably a mistake in ad169ba67a ?

3.6 LTS can read the file

Short description of error
This file immediately crashes on startup. Unfortunately I don't think I can isolate the issue to the crash-causing objects, and have to upload the entire project file, so I'm sorry for the 50 mb .blend. There are some linked libraries associated with it, but it still crashes when those libraries are missing from the expected path, so I'm guessing that they're not related. I have tried appending the collections into a new file, the collections that cause the crash (which also crash on appending) are some of the iced_manfiold collections (iced_manfiold.002 and iced_manfiold.003 I think?)

That is all the relevant information I can think of for now.

Probably caused by ad169ba67a

One thing that crashes:
Object : Plane.006
Modifier : FX-ice_over

The modifiers blend_read tries to go over NodesModifierBake ( NodesModifierData has bakes_num set to 1, but the modifier does not even have a Nodegroup, not sure how that happened... ), so that points to garbage memory...

CC @JacquesLucke preventing the crash on file read (when we dont even have a nodegroup) is probably simple, but it might be worth investigating why this can even happen on write?)

If it helps, FX-ice_over is a linked geonodes modifier from another file. It had a bake node in the tree, but I don't believe it was actually baked in either the library file or the main file.

Thanks. I can reproduce the issue. Will try to figure out what caused it.

@Albert-OShea Do you also get the crash even when the FX-ice_over node group is available, or does it work in this case?

[EDIT] Nevermind, just saw that you answered that already in the bug report.

I looked a bit into it, but still don't have an idea for what the root cause is. Somehow some data is missing in the file.

  • Can you tell us the commit hash of the Blender version that you saved the broken file with?
  • Is there a possibility that you opened and saved the file an an older Blender version than the one you mainly worked with? (not sure if that could cause an issue here, but maybe)

@JacquesLucke I'm not at the same computer to get the exact hash, but it should just be the 4.1.1 release, would the hash change for that version after its release?

Edit: the hash is e1743a0317

And no, I never opened it in an older version than 4.1.1

I do have the FX-ice_over file here though, if that would help you
