Hi,
Before you try to use the cron for a mass action, it's best to use the "process" button to launch the mass action manually.
That way, if you have an error with it, you should be able to see it on the screen.
What do you see when you run the mass action manually ?
Once you know the mass action is filtering properly, and generating the XLSX file when you manually process it, you can check that your cron task itself is working:

If you get an error with the cron, turn on the "debug" setting of the Joomla configuration and try again. You should get an error message with more information. That will be important to better understand the problem.
