The rendertype_armor_cutout_no_cull, rendertype_breeze_wind, rendertype_energy_swirl, rendertype_entity_cutout_no_cull_z_offset, rendertype_entity_cutout_no_cull, rendertype_entity_cutout, rendertype_entity_no_outline, rendertype_entity_smooth_cutout, rendertype_entity_solid, rendertype_entity_translucent_emissive, rendertype_entity_translucent and rendertype_eyes shaders now use the entity.fsh and entity.vsh programs, fyi

I want to add in a Comment here as I have found the issue.
Yes, This IS a Minecraft bug.

I went further into this and Decompiled both 1.21.3 and 1.21.1 jar file versions to find that 1.21.3 is missing these two shader program files. rendertype_armor_cutout_no_cull.vsh (Vertex shader program) and rendertype_armor_cutout_no_cull.fsh (Fragment Shader).

Which that log you have gotten is complaining that Minecraft can't find the VERTEX version of the shader program (rendertype_armor_cutout_no_cull.vsh). Of course it will not be able to find it since in the 1.21.3 version of Minecraft. The files which hold those programs do not exist.

Currently, the only fix is to run on 1.21.1 sadly as that version has the required shader program.

Hope this helps someone as I have been struggling with it for a while.

In my opinion this is not a bug. The resource is not 1.21.2+ compatible, because it mentions shaders that does not exist. The core folder needs to be added in the vertex and fragment fields in the json file. This changed in 1.21.2.

I attached a fixed version, where I've updated the resource pack to 1.21.2.

Have not tested/updated/fixed functionality, only fixed the pack loading.
