这个错误可能是因为程序运行出现问题后程序被强制退出，然后出现了AttributeError: exit。你可以尝试以下几个解决方案：

1. 尝试在程序开头添加以下代码，以捕获程序异常并禁用Python的缓冲机制：

import sys
sys.tracebacklimit = 0
import os
os.environ['PYTHONUNBUFFERED'] = '1'

2. 检查是否有其他程序或进程占用了要素类或者表格，导致程序无法正常执行。你可以尝试手动删除要素类或表格，然后重新运行程序。

3. 确认所使用的参数是否正确，特别是输入和输出数据的路径是否正确。你可以在程序中添加一些输出语句，输出参数的值，以便检查是否正确。

可以尝试将第 25 行的 `del cursor` 改为 `del cursor, join_layer`，因为需要同时删除游标对象和要素图层对象。修改后的代码如下：

import arcpy

# 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)

# 创建空间连接
join_result = arcpy.SpatialJoin_analysis(input_features, target_feature, "in_memory/spatial_join", "JOIN_ONE_TO_ONE", "KEEP_ALL", "", "INTERSECT")

# 使用MakeFeatureLayer创建要素图层，并使用AddFieldDelimiters处理字段名称
join_layer = arcpy.management.MakeFeatureLayer(join_result, "join_layer").getOutput(0)
join_field_name = arcpy.AddFieldDelimiters(join_layer, join_field)

# 使用SelectLayerByAttribute选择重叠面积大于阈值的要素
arcpy.management.SelectLayerByAttribute(join_layer, "NEW_SELECTION", "Shape_Area > " + str(area_threshold))

# 使用SummaryStatistics工具进行面积求和
summary_table = arcpy.Statistics_analysis(join_layer, "in_memory/summary_table", [["Shape_Area", "SUM"]], join_field_name)

# 使用TableToNumPyArray将结果转换为字典
sum_dict = {}
with arcpy.da.TableToNumPyArray(summary_table, [join_field, "SUM_Shape_Area"]) as arr:
    for row in arr:
        sum_dict[row[0]] = row[1]

# 使用UpdateCursor更新目标要素类的目标字段
with arcpy.da.UpdateCursor(target_feature, [target_field, join_field], sql_clause=(None, "ORDER BY OBJECTID")) as cursor:
    for row in cursor:
        join_value = row[1]
        if join_value in sum_dict:
            area_sum = sum_dict[join_value]
            row[0] = area_sum
        cursor.updateRow(row)

# 导出结果
output_feature = arcpy.GetParameterAsText(5)
arcpy.CopyFeatures_management(target_feature, output_feature)

# 删除游标对象和要素图层对象
del cursor, join_layer
