I'm currently using Tableau 2020.4 and I have been getting the error code "Error Code: EA3F4C1E" a lot lately.
An error occurred while communicating with data source '
Bad Connection: Tableau could not connect to the data source.
Error Code: EA3F4C1E
InsertData: unbound column
FYI- My xlsx data source is currently 52,281 KB and is updated / added to several times a week. The file name, column headers, and network location are all the same.

I ran into the same issue. To get around it I saved the bad/corrupt Excel file as a .csv and then opened the csv file with Excel and resaved the Excel file as .xlsx This seems to have gotten around the corruption in the Excel file.
