ue5-main PostProcess Volume Details Crash dues to BrushType nullptr FPropertyNode.
The property path that fails is “BrushType”
Steps:
Create a Post Process Volume Actor, or select one in one of your scene

Commenting out this line in BrushDetails.cpp will fix it.

//BrushBuilderCategory.AddProperty( GET_MEMBER_NAME_CHECKED(ABrush, BrushType) );
