Can't open exported .xlsx file

I'm trying to open an exported .xlsx file but I got this error from Excel:

Excel cannot open the file "file.xlsx" because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file.

I opened the file in text format and got this error:

Invalid parameter: Card 9 does not have a template tag named nil.

Metabase version is 0.45.1 and it reads from MySQL 5.7.38 as a data source.

Could you help please?
