I am running a daylight autonomy script. However, when I turn the toggle to true, I get a “Solution exception: WindowsError”

Would appreciate any help. Thanks

It’s somewhat hard to make out from that image, but that possibly looks like Ladybug?  
If so, please see [https://discourse.ladybug.tools/](https://discourse.ladybug.tools/) for questions and answers related to that plug-in.
