Failed to open material with empty embed texture

[Phyksar]

Describe the bug
Tried to figure out how you would embed a texture inside a material like base/fx/vehicles/common/shadow_mat.mi and now my material isn't even opening.

To Reproduce
Steps to reproduce the behavior:

1. Copy any material to project.
2. Create an embed xbm texture by pressing a "plus" icon in the material browser.
3. Save material with an empty texture because WolvenKit doesn't offer any way to upload an embed texture.
4. Close and try to open material again, you get an error:

[27.03.2024 8:46:44] [Error    ] Message: Object reference not set to an instance of an object.

Expected behavior
The material browser should open no matter what state of resources it has.
