Additional Information
This behavior is as designed. var fcName = selectedLayerTable.GetName();, returns fully qualified name (database_name.schema_name.table_name) FeatureClassDescription does not allow dot (.) or other special characters in a feature class name. Strip database_name.schema_name from the feature class name before reusing it, as shown in the sample snippet below for enterprise geodatabases. var fcDescription = new FeatureClassDescription(fcName.Split('.').Last(), fieldDescriptions, originalFeatureClassDescription.ShapeDescription);Workaround
As a temporary workaround, manually add the required fields using the Add Field geoprocessing tool in ArcGIS Pro. Refer to https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/add-field.htm for more information.
