System Information
Operating system: macOS-12.6.7-arm64-arm-64bit 64 Bits
Graphics card: Metal API Apple M1 Max 1.2

Blender Version
Broken: version: 3.6.6, branch: blender-v3.6-release, commit date: 2023-11-22 18:47, hash: 064a48ad28e3 (also crashing in 4.0)
Worked: (newest version of Blender that worked as expected) Earlier version of 3.6, issue only arose since 3.6.5 I believe

Short description of error
A number of shot files (with library overrides) crash after save and reload. Haven't found a common factor so far.

Exact steps for others to reproduce the error
Open PosterPoses-01, for me it crashes every time (libraries will be missing, but hoping it still works enough to demonstrate)
PosterPosesremaprelateive-02 loads for me. I just did the remapping as a test, it already was loading.

Attaching here a couple of tracebacks from 2 different crashing files. Also attaching an example full Apple crash log

Many thanks in advance for checking it out!

Hi, thanks for the report. Unable to redo the crash locally on Windows. Stack-trace has dependency graph related functions.
Guess we would require linked libraries to trigger the crash.

Thanks Pratik, I just confirmed the same here. Tried the files on Windows and they open. But on my M1 Mac, PosterPoses-01 crashes every time. Is it possible to test on Mac silicon there? It seems it's a Mac only issue and has happened on a number of shots on my (normally Mac only) production recently.

Are they required for crash?

Is it possible to test on Mac silicon there

Unfortunately, I don't have. But @mano-wii may able to check 🙂

The linked libraries are big files. The supplied files will report them missing (as it does on Windows though they still open), but that in itself shouldn't cause the crash.

Poster-Poses-01 gives a seg fault every time on my Mac, and for comparison, Posterposes-02remaprelative opens fine on my Mac.

Would be great if @mano-wii is able to reproduce the crash. Thank you so much!

It loads here, but with tons of information and warnings about linked libraries.
I believe the crash really depends on the linked libraries.
Please try to simplify the files and narrow down the problem by removing most objects and disabling the settings, until the problem reveals itself more clearly.

Unfortunately we can't do much here.

Interesting that it loads for you @mano-wii thank you. I have tried stripping blender back to factory defaults, but still had the crash. And I've just had another shot I was working on, all fine. But then crashes on reload. This is a hard one to troubleshoot, as when it happens, I can no longer open the file.

As suggested, I'll continue trying to narrow down the trigger, maybe adding one asset at a time to a scene file

Ok I've done a lot of experimenting, stripping back of scenes etc. and it seems this is related to the Asset Library/Browser

In brief I found that:

crashes seemed to be related to a particular rig
scenes where this rig was manually linked in via File>Link menu were fine, BUT if linked in via the Asset Browser, the scene file would crash upon save and reload.

I stripped back that rig (Matil) bit by bit, as I thought it might have been related to some mesh or modifier within the rig file. In the end, with some slightly variable results, the only version that would reliably work (i.e. not trigger a crash) after stripping back had no geometry, only the armature.

So I'm attaching here a small hierarchy with a very stripped down version of the rig, which gives reproducible crashes for me. Here are my step-by-step instructions to reproduce (I hope)

On Mac Silicon (mine is M1 Max Studio) Unzip the MatildaCrashSubmission.zip somewhere convenient, leaving folder structure intact
In your Blender preferences>File Paths>Asset Libraries add the enclosed 'asset' folder to your list and set import method to 'Link'
Open the file 'CrashTestAssetBrowser-01.blend'
In the asset browser select 'uncategorised', you should see MATIL-DAY and MATIL-DANCE (yes two libraries in one file, character variants with shared rig, but this has been normal/useful/essential for my workflow for ages)
Drag and drop MATIL-DAY to the 3D viewport
alt-G to zero out translation, then Object>Library Override>Make
Save the file
Save and Reload or Revert the file >>>> crash (if not the first time, try at least a couple of save-reloads. Sometimes it loads the first time, weirdly) Attaching example crash.txt here.

Assuming you get a crash, you can compare with the manual method, which doesn't seem to crash, i.e.:

(after step 2 above)

Open the file 'CrashTestLink-02.blend'
File>Link ../asset/Matil.blend
Link collection MATIL-DAY
Object>Library Override>Make
Save the file
Save and Reload or Revert (try a few times to confirm). No crash probably

Very much hoping this works for you and sheds some light on what's going on. Is it some sort of corruption in the Asset Library file?

Some further hints based on more experiments:

I hit a situation where manually linking the Matil rig (ie. not with asset browser) still gave crashes on reload.

So I tried again using asset browser. What I have found :

1.Drag and drop etc. then using Menu Object>Library Override>Make is still giving crashes on scene reload frequently (attaching sample crash report)
2. Using RMB menu in outliner Library Override>Make>Selected and Content is giving stable results, no crashes so far.

Let me know if you get a chance to test again @mano-wii or if you want me to try something else.

Best regards, Stephen.
