Odoo 15导入product.product模型时出现Savepoint错误求助

在Odoo 15中通过Excel导入产品时，仅product.product模型出现异常，错误日志显示与保存点缺失、事务回滚相关，具体错误输出如下：

The above exception was the direct cause of the following exception:

psycopg2.errors.InvalidSavepointSpecification: 保存点 "model_load" 不存在

已尝试的操作：

• 检查自定义代码：仅对product.product做了两处修改——更新WooCommerce价格、重新分配重复产品
• 手动测试：通过UI创建产品正常
• 重启PostgreSQL和Odoo，问题依旧
• 检查数据库锁：无活动事务阻止导入
