What is the issue?

Hi, when I run "ollama run "x/z-image-turbo:latest" (or flux2, the same), I get (MacOS, Apple Silicon):
ollama run "x/z-image-turbo:latest"
Error: failed to load model: 500 Internal Server Error: mlx runner failed: model.norm.weight (exit: exit status 1)

Same for ollama 0.16.0 (it worked a few versions ago, don't remember which one exactly, but it's not long ago)

Relevant log output
