为什么Task Scheduler无法运行我的Python脚本

我正在尝试使用任务计划程序运行python脚本，我已经编写了一个批处理文件；

"C:\Program Files\WinPython64\python-3.7.7.amd64\python.exe" "C:\Users\USER\Documents\Python_Code\python3.6\Web_Scraping\Firmware_Upgrade\Set_Check_Upgrade_v7.py"

其中的一个简单的Hello World类型示例。

当我尝试运行实际代码时，我收到以下错误消息；

C:\Windows\system32>"C:\Program Files\WinPython64\python-3.7.7.amd64\python.exe" "C:\Users\USER\Documents\Python_Code\python3.6\Web_Scraping\Firmware_Upgrade\Set_Check_Upgrade_v7.py"

    with open(filename,"rb") as f:
FileNotFoundError: [Errno 2] No such file or directory: 'Upgrade_v5.22_01-08-2020.xlsx'

我使用的python代码是

file_string = 'Upgrade_v5.22_01-08-2020'
total_string = file_string + '.xlsx'

firmware_data = pd.read_excel(total_string)

在Pycharms IDE中运行但不使用Windows 10 Task Scheduler App时可以使用。

Excel文件与Python文件位于同一目录中。

我尝试创建启用了“以最高特权运行”的任务，但这没什么区别。
