XLRDError: Unsupported format, or corrupt file: Expected BOF record; found b'\r\n\r\n\r\n\r\n'

I tried to convert a xls file into csv with the following command, but failed:

$ in2csv --sheet 'Sheet1'  2021-2022-1.xls
XLRDError: Unsupported format, or corrupt file: Expected BOF record; found b'\r\n\r\n\r\n\r\n'

The above testing file is located at here [1].

Any hints for fixing this problem?
