Power BI Desktop Refresh error

[Jay_2022]

I am using Oracle as my data source. I was able to establish a connection and import all the necessary tables. I even build a report and saved as .pbix file.
When I reopen the saved ***.pbix file and refresh it from the desktop or when I open the file and go to the query editor, I am getting the connection error.

Thank you. I have both 64-bit and 32-bit version on my PC, but my oracle drive is 32-bit. I need to make sure that I am using 32-bit version.
