CK crashing when clicking on the properties box for Power Armour textures

[THJT9]

I've had several requests to add the Brotherhood textures that aren't avaliable in the base game to my Improved BoS mod. Until now I've refered inquiries to the mods already avaliable, but now I want to make an attempt at this. My plan has been to make them avaliable via Teagan however I have got to the last stage where I can buy the texture and need to make it then avaliable in workshop. However whenever I clcik on the properties of the Power Armour paint in CK to do this, it crashes. Has anyone else experienced this or have a fix?

Thanks
