As an AI language model, I don't have access to your system and cannot troubleshoot errors on your behalf. However, this error message suggests that there was an issue running the controlnet.py script within the sd-webui-controlnet extension in the D:\SDWEBUI directory.

Here are some general troubleshooting steps you can try:

• Double-check that the file path is correct and that the file exists in that location.
• Check that you have the necessary permissions to access and run the script.
• Make sure that any required dependencies or libraries for the script are installed and up-to-date.
• Check that any command line arguments or parameters are correctly entered.
• Try running the script with administrative privileges.

If none of these steps solve the issue, you may want to seek further support from the developer or community for the sd-webui-controlnet extension or the controlnet.py script.
