Hello,
Please deactivate all the plugins except these ones:
Slider Revolution
Elementor
Woodmart Core
Contact Form 7
MailChimp for WordPress
WooCommerce
Safe SVG
Switch to the parent theme and check, If the problem has gone, activate the plugins one by one, checking the issue to detect which one causes the problem. If the issue remains, share the wp logins details so I will check and give you a possible solution.
