Excel file is not opening while export data in excel, but working fine in localhost

Question

I face some problem in excel file. I am exporting excel file with data. This code is working fine in localhost. But in live server, the excel file is not opening and display message as

Excel cannot open the file "users_download_.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.

My controller code is:

<?php

declare(strict_types=1);

Any help will be appreciate. Thank you.
