这个错误通常发生在程序结束时，尝试执行一些无法完成的操作时。建议检查你的程序是否有其他错误，导致它没有正常结束。你可以使用try-except语句来捕获和处理异常，在程序结束前进行清理工作。例如：

import arcpy 

try:
    # 获取参数
    input_features = arcpy.GetParameterAsText(0)
    join_field = arcpy.GetParameterAsText(1)
    target_feature = arcpy.GetParameterAsText(2)
    target_field = arcpy.GetParameterAsText(3)
    area_threshold = arcpy.GetParameterAsText(4)
    
    # 其他程序代码...
    
except Exception as e:
    arcpy.AddError(str(e))
finally:
    # 删除游标对象和要素图层对象
    del cursor, join_layer

这个try-except语句会捕获所有异常，并在程序结束前进行清理工作。如果程序发生异常，它会输出错误信息并退出，否则它会正常结束并删除游标对象和要素图层对象。
