Error: Couldn’t find PHP CLI executable

I’m working on backing up my site before updating my PHP (currently on 7.3, looking to upgrade to 8.1), when running this plugin, I receive an error saying that it was unable to locate the PHP CLI executable. It stops backing up at around 63%. Attached is the error report, any help is most appreciated!
