Sometimes these things happen because of a conflict with another plugin, or an incompatible PHP version running on your hosting server, or an incompatible version of WordPress core.
What version of WordPress are you using? What PHP version are you running?

I see it's the Pro version that has the latest version number of v2.8.4. The latest free version is v2.9.2.
Do you have a copy of the previous version you were using? Reverting the plugin back to the previously installed version is probably a low effort option. The problem may resolve itself later when a new release becomes available.
Either way, Elementor must fix their code, so an Elementor support ticket is required.
