Please follow this troubleshooting method that I made: (It’s quite general, but it will tell us something.)
Please make sure that all of your Plug-ins and Theme are updated.
Sometimes it isn’t obvious that there is a plugin update available. Go to WordPress Dashboard > Updates and click the Check Again button to be sure.
Please also regenerate the CSS via Elementor > Tools > Regenerate CSS on your WordPress Dashboard,
then make sure that you are clear:
your WordPress cache (your WordPress plugin if you have one), your server cache (if
you have one. In this case, you can contact your hosting provider).
Please deactivate all your plugins besides Elementor and see if it helps. If it solves the issue, reactivate them one by one to find the culprit. If it didn’t help, switch your theme (temporarily) and see if it makes any difference.
