After the latest update, I can’t start ComfyUI. Seems everything well in Troubleshoot. And I also tried to reinstall it, but the issue still there. I got an error message in main.log. and I’m not sure if it’s the key problem. [2026-01-09 09:51:57.038] [info] Server start [2026-01-09 09:51:57.075] …

figured it out, uninstall and make sure to go to custom and check off everything then reinstall it. It will be a fresh install.

已经找到办法，更新了驱动之后就能正常使用，驱动程序里选择“studio驱动程序”，在图中也说明了，这个驱动可以提升comfyui，
