Please deactivate all the plugins except these ones:
Slider Revolution
WPBakery Page Builder or 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.
After disabling all plugins the issue is gone. Most likely the issue comes from the “Lazy loading” functionality of the “WP Rocket” plugin so navigate to the settings of it and disable the lazy load (more detail in the below screenshot).
