Automation error: A Task was Canceled?

[KEI72]

(Disclosure; I am not the original author of the apps and have been learning appsheet as I make changes and troubleshoot for this company) 

We have a vehicle mileage app with an automated manual report function that is used to create a xlsx report of mileage anytime a report is requested. 

This function was working just fine, then one day the loading took longer and the automation stopped working, I checked the template and formulas but couldnt see any issues,

Anytime I Test the automation it loads for about 2 minutes and gives the Error "A task was Canceled" 

Template File 

Any suggestions appreciated. Let me know if you need more information

Ive Tried:

- Verifying data via save drop down

- remade the automation deleted the old one

- made the automation send an email with template as attachment instead of creating a file

- turned it off and back on lol.
