  1. Use an FTP program to deactivate your plugins by modifying their names. This will give you access to WP Admin.
  2. After you have regained access, use an FTP program to upload  Elementor / Elementor Pro to your WP files. Put them in the wp-content > plugins directory.

If you do not know how to reach or modify the plugins names using FTP, contact your hosting provider.
