ArcGIS Pro 3.6 fails to open a DWG file and returns the error message “External component has thrown an exception".

Workaround

Open the DWG in C3D. In Toolspace, click the Settings tab, expand Point, and select User-Defined Properties. Click Unclassified. In the table that opens, for the Additional Descriptions property, check the Default Values check box. Save the file and open it in ArcGIS Pro.
