1.19.3 Missing Texture

Hello, I made all the necessary changes for the 1.19.3 (resource pack) but it does not work.

Item Adder generates automatically the atlases file but the textures are still missing

I need help or clarification on how it works.

did you try the golden rule?

/iareload

/iazip

/iatexture all

If you are using other plugins texture plugins make sure to reload them also
