Javascript error after update

Just updated to latest version of Smart Grid-Layout Design for Contact Form 7 and now have a Javascript error that is causing my instagram feed to not display.

Confirmed it’s the CF7 Grid plugin having issues, as when I deactivate the instagram feed works again (bottom of page just above footer). Re-activated the CF7 Grid plugin so contact forms work but need to get the Instagram feed working.

Any idea on how I can resolve the error below…

Uncaught TypeError: Cannot read properties of undefined (reading 'submit_disabled')
