try to run other workflow to see if ComfyUI is the problem but other can run well. Already do the update all using manager.

I suspect that the checkpoint may be corrupted. Could you please verify its integrity? The size should be approximately 1.8GB. Alternatively, you might want to try re-downloading the checkpoint mm_sd_v15_v2.ckpt.
