There is a known issue after Elementor update, which is weirdly related to the WordPress admin bar. Try navigating to Users ->Profile and clear the “Show Toolbar when viewing site” checkbox. Once it is done, check whether the issue is resolved.
This is a temporary solution and we are currently working on finding out whether the issue is on our or Elementor end. If the issue persists, submit your request to our Help Desk providing a temporary access to your WordPress dashboard, so we take a closer look at the issue.
