UE 5.3.2 Crashing on "Sync Content"

Hello, whenever I attempt to use the “Sync Content” function with Git version control in UE 5.3.2 I am getting a full crash. This happens on any project, including a brand new blank one with no starter assets. The error message is as shown below:

Assertion failed: !GDefaultMaterials[Domain]->HasAnyFlags(RF_NeedPostLoad) [File:D:\build++UE5\Sync\Engine\Source\Runtime\Engine\Private\Materials\Material.cpp] [Line: 712]

I’ve searched up this error and most of what I’ve seen seems to be pretty specific to materials in use, textures, foliage etc but nothing about it being attached to the “sync content” source control feature.

Hello there! I just wanted to ask if you managed to figure out what’s going on? Running into the same situation but with Perforce. Also 5.3.2 however using a source build.

Did a couple of quick tests:
I can reproduce it on 5.3.2 launcher version as well. However not on 5.2.1 launcher version.

I have not been able to find a fix for this yet unfortunately. It seems based on the error that this is an engine error that may have recently been introduced but I’m out of my depth trying to figure out more of the specifics.

Did anyone find a solution? We sync the content with the perforce client, but to be fair it would be more convenient to sync with the editor.
