There is. Please download alpha build from https://builder.blender.org/download/daily/ and run file blender_debug_log.cmd. After crash upload created files. However these logs are not enough to fix the bug. We still need .blend file and steps to reproduce the crash.

Well, it seems I managed to do a change in the source file I'm linking from that causes instant crash in my project file in 4.0 (3.6.1 still opens it without crashing). The trouble is reverting the source file from the blend1 backup doesn't seem to help.

EDIT: Did some more testing. If I rename my source file, I can open the file with the linked overrides. If I then rename the source file back while having the linked file open, and do a "find missing files", it re-links everyhing... except no meshes show up (old issue), and once I save and re-open it instantly crashes again.

Another issue is that problems often go away when I try to remove everything but a few objects of interest. I absolutely cannot share the entire files, since it's a project at work using the latest product we're launching. I've mentioned this before, but if I can get a developer to sign an NDA, I could share the files, but I guess Blender devs don't work that way.

Library overrides get reset when the linked file changes #110742

You can send the file via email, you will have to trust us (I guess me) that we keep the file private. You can find mail in my profile

I'm afraid that for the data contained in this project at this time we need a bit more than "trust me bro". If the developer assigned to this bug is employed by the blender foundation and has a blender.org e-mail and is willing to sign an NDA, then we can send a secure link to the project files. That's probably the only way, unfortunately.

You can send it to richard@blender.org, but signing NDA is a bit useless. I would still have to share files with other developers, unless I manage to recreate the issue from scratch.

Any updates here?

I sent the mail with the NDA on the 17th. Haven't heard anything back.

Sorry, I don't check that email very often (means almost never).

From what you send me and crash log, the NDA would have to be signed by @mont29 with blessing of @fsiddi. Will leave that decision up to them then. If they are willing to sign anything, I can forward the NDA.

This has been discussed in chat, and to summarize, we would not accept files under NDA. If you need support in this case we can recommend to use professional support like Cannonical.

I see reports about overrides pop up relatively often still, so it is possible this will be resolved anyway. In any case, without file or steps to reproduce, will have to close this report. If you find a way to reproduce from scratch, please make a new report.

Crash loading file with library overrides and object-linked materials #111907

Hi @RobertS

I believe I managed to reproduce a similar crash as the one you've encountered, since the error log points to a similar location in the code: #111907
Subscribe to that issue if you want to be notified when the bug gets fixed :)

EDIT: Seems like you're having a crash on 3.6.1 while my file worked in that version. So maybe it's unrelated after all...
