Custom banner always crashes the Creation kit

[P0188]

every time i try to produce a texture set with my texture it immediately crashes. i dont get it, am i 2 pixels off of the right size or somthing and why is the CK so picky?

 

i extracted a generic banner texture with BAE and layered over my banner almost pixel perfect, exported as .dds with compression of DXT5, and generated mipmaps which i believe to be the correct processes.

 

ive been doing this for such a long time i think im starting to lose braincells.

Okay im dumb. i did some more scouring and i found this post: https://steamcommunity.com/discussions/forum/1/627456359660978688/

 

essentially the issue was that the texture should be a mutliple of 32 (32x32, 64x32, 128x64, 1024x64 etc).
