Hello,
It is recommended to run import on a fresh WordPress installation. For this you can use WordPress Database Reset plugin https://wordpress.org/plugins/wordpress-database-reset/ The plugin can be used to remove all the existing content and install a new version from scratch. Please do the reset and reply with temporary wp-admin and FTP access here. We will help you with the import. https://xstore.8theme.com/elementor/demos/niche-market02/
