Explorer crashes and .bat files failing to launch when running ComfyUI (RTX 4090 / 9950X)

(English corrected by AI for better readability) Hi everyone. I’m very new to local AI workflows. I’m a Windows user without a deep understanding of Python or highly technical backend processes, so I’d appreciate some guidance. My Hardware (Windows 11 Pro): GPU: RTX 4090 (Power limit 100%, sometimes running a VF curve at 2.9GHz/1.07V) CPU: Ryzen 9 9950X (PBO enabled: -5 ccd0 / -12 ccd1 - very conservative) RAM: 64GB DDR5 (No OC, but tight timings) Storage: ComfyUI portable versions are running on a dedicated NVMe Gen4 drive (not the C: drive) with plenty of space.
