must not already be a layered image

Error message

must not already be a layered image

What it means

TextureReinterpretationError (already-layered guard): the image is already a layered/array texture, so it cannot be reinterpreted from a plain 2D image into a layered layout again.

Solutions

1. Only reinterpret images that are not already layered (single-layer 2D)
2. Skip reinterpretation when the image already has array layers
