Hello,
Thanks for contacting us.

Was XStore Core plugin installed successfully before the import?
Make sure that all 3rd party plugins are disabled before the import. Also, you do not need to install all bundled plugins from the start.
Demo content can be imported incorrectly in case a lot of 3rd party plugins were activated on the site before the import. In this case, provide temporary wp-admin access, we will help you.
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 access here. What demo version do you want to install? Do you prefer Elementor of WPBakery?
Regards
