Hi Candice,
Thank you for posting your concern.
According to Note section in this guide, Preview is not currently working with this script. It creates product groups and subdivides them further, but because the product groups are not actually created in preview mode, attempting to operate on them fails. The script will still work when run normally.
With this, you may try to Run the script. If the script will not work even after running the script, so I can further investigate the issue, could you provide the script name and your customer ID where you implemented the script via Reply privately to author?

Hi Candice,
Glad to hear that the script is working now.
However, it is currently not possible to increase the time limitation. With this, what you can do is to create separate instance of scripts, then lessen the data in the spreadsheet to bulk create ad groups and product groups to avoid the timeout error.
Please let me know if you have further clarifications.
