I wonder if you might have installed AutoCAD 2025?   At this time, Ansys Thermal Desktop is not compatible with AutoCAD 2025.   That compatability will be released July 2025.   

If you installed AutoCAD 2024, and you are receiving this error, then please just try to reinstall Ansys Thermal Desktop and see if that fixes the issue.
