Packaging UE5 project produces GDefaultMaterials[Domain] != nullptr assert, sometimes

Development Asset Creation

Hi, it’s the first time we tried a development package build on UE5.
We had it running successfully on all sorts of machines, but some users are reporting the following assert:

Assertion Failed:  GDefaultMaterials[Domain] != nullptr
[File D:/build+ +/UE5/Sync/Engine/Source/Runtime/Engine/Private/Materials/Materials.cpp] [Line: 579]
Cannot load default material
'engine-ini:/Script/Engine.Engine.DefaultMaterialName'

What’s weird is that that looks like a config bug but it will happen only on a few machines, in particular on a:

an i7 10700F @2.9Ghz with 16 GB RAM and running GForce RTX 3060

Does anyone have any idea?

Cheers,
Dado.

I have the same question. Did you make any progress?

Unfortunately I don’t think we ever figured out any of those issues we had on packaged builds, we have all sort of errors and no real pointers anywhere.
