I also had this problem.
Temporary solution:
edit class-advanced-cf7-db-admin.php
Chenge

	function vsz_contact_form_callback(){
		//Check current user permission
		if (!current_user_can('manage_options'))  {
			wp_die( __('You do not have sufficient permissions to access this page.') );
		}
		wp_enqueue_style('vsz-cf7-db-admin-css');
		//Define all entry related design in this file
		require_once plugin_dir_path( __FILE__ ) . 'partials/contact_form_listing.php';
	}

for this

		// Callback function for listing screen
	function vsz_contact_form_callback(){
		//Check current user permission
		if (!current_user_can('administrator') && !current_user_can('editor')) {
			wp_die( __('You do not have sufficient permissions to access this page.') );
		}
 
		wp_enqueue_style('vsz-cf7-db-admin-css');
		//Define all entry related design in this file
		require_once plugin_dir_path( __FILE__ ) . 'partials/contact_form_listing.php';
	}
