I'm trying to switch CHECKPOINT to XL, but it gives an error.

When switching between other models, everything switches well

check if stable-diffusion-webui\repositories\generative-models\configs\inference\sd_xl_base.yaml is missing for some reason
if missing then delete stable-diffusion-webui\repositories\generative-models to let webui re-download it on next launch
if it is there then something else is going on
