Start by reproducing the Windows startup failure and inspect the CUDA warning in torch\cuda\__init__.py. Trace the initialization path through comfy/model_management.py, execution.py, and main.py, especially get_torch_device and current_device. Done means Comfy Desktop starts without the access violation on the affected system.
