Traceback (most recent call last):

ValueError: pipeline source not found or not recognized: runwayml/stable-diffusion-v1-5

This is caused by the new path.exists check when trying to detect if a path is a Diffusers folder or checkpoint file. The pipeline.from_pretrained method downloads the files as they are needed, so they don't exist yet, and the check doesn't know what to do.
