I think you will want to add a null ptr guard for Texture from NoesisXaml->Textures in UNoesisXamlFactory::FactoryCreateBinary line 570 (3.2.10). As I managed to crash in there once when reimporting a Xaml asset.

// Make sure textures have alpha premultiplied if the user needs them, or are cleaned if they already are
for (auto Texture : NoesisXaml->Textures)
{
    if ((Texture->LODGroup != TEXTUREGROUP_UI ||
        Texture->SRGB)) // crashed here with a Texture as nullptr
    {

I can't remember the exact situation that caused it to end up as null, it was something like saving the xaml uasset, but not one of its imported textures, then next run reimporting. I haven't repro'd it since, but it did crash in there. Either should be guarded or some sanitation checks.
