Hello,
Provide us with FTP access to your site, please. It looks that at this moment you can edit shop page using Safe mode only because of js error. We need FTP to find out what gives that error. Anyway, I hope you understand that you’ll be able just to add content before products editing the shop page. You won’t be able to edit its layout. If you want to edit shop page layout using elementor follow the docs https://elementor.com/help/creating-a-woocommerce-archive-template/
Regards
