Unable to import texture to material editor

I was following this tutorial, when it required me to add a texture to a material. It is called T_AlpinePatch001_D_alt_R, and it comes from the Open World Demo Collection. Whenever I try to interact with this texture, UE4 freezes. Any other texture is fine, only this one causes it. I’m on Mac btw.

To recreate this problem, follow this tutorial to the letter on a Mac.
