There could be a JavaScript conflict with other Elementor plugins or you need to increate the memory used by your Wordpress.

To increase the memory you can edit your wp-config.php file and add this row.

define('WP_MEMORY_LIMIT', '256M');

If you still have the problem you can increase it to 512M

define('WP_MEMORY_LIMIT', '512M');

The memory you need depends on how many features you enabled.
