Hi @nezzazvoni,
I have checked your website and enabled the global options in Slider Revolution for Deferred JavaScript and Insert JavaScript in Footer which makes the slide loaded a little faster.

I have also found that a JavaScript console error is showing on your site, which might be another reason for your issue.
I would suggest you do troubleshoot a few common issues to detect the problem.
1.Theme Related Issue
2.Plugin Conflict
3.Theme Update related issue
4.Child Theme Related issue
5.CSS/JS Customization
6.Disabling Cache
7.Disabling CDN
If you discover that an issue is coming from a custom code or 3rd party plugin, kindly consult with a developer or contact the plugin author. Please note that we do not provide support for custom codes and 3rd party plugins.
If the above points do not resolve your issue, please copy your live site to a staging server so we could troubleshoot freely without breaking your live site.
And give us access in the secure note including:
– WordPress Site URL & Login URL
– WordPress Admin username/password
To create a secure note, click the key icon underneath any of your posts.
Thanks
