Hi, chulpanvl 

 

Not sure if the latest version of python is supported according to the doc. 

More details:

Learn which Python packages are supported - Power BI | Microsoft Docs

Create Power BI visuals using Python in Power BI Desktop - Power BI | Microsoft Docs

It is recommended to use an older version of python, and powerbi desktop and gateway can be downloaded the latest version normally. 

I suggest you open the data source settings in desktop and delete the previous credentials and update it. Delete the original report in the service and re-publieh the report.

 

You can create a simple sample file to see if there is a problem.

Did I answer your question? Please mark my reply as solution. Thank you very much.
If not, please feel free to ask me.

    Are you using a normal python environment and using an older version of python? Does it refresh properly on the desktop? If not, please show a screenshot of the error message.
