Thank you for sharing these details, but the website seems to be inaccessible with the "This site can’t be reached" message.
During some further investigation, I found another report about a similar issue, for which a fix is planned in the upcoming releases.
For now, you can follow these steps:
1. Please make sure that from Toolset plugins only Types, Blocks, and Module Manager plugins are active with the latest versions.
2. Look for a file named "m2m.php" in folder:
wp-content/plugins/toolset-blocks/vendor/toolset/toolset-common/inc/public_api/
Starting from line #494, you'll see this code:
$import_associations = Toolset_Singleton_Factory::get( '\OTGS\Toolset\Types\Post\Import\Associations',
Toolset_Singleton_Factory::get( '\OTGS\Toolset\Types\Post\Meta\Associations' ),
Toolset_Singleton_Factory::get( '\OTGS\Toolset\Types\Wordpress\Post\Storage', $wpdb ),
Toolset_Singleton_Factory::get( '\OTGS\Toolset\Types\Wordpress\Postmeta\Storage', $wpdb ),
Toolset_Relationship_Definition_Repository::get_instance(),
$association_repository,
Toolset_Singleton_Factory::get( '\OTGS\Toolset\Types\Post\Import\Association\Factory' ),
);
Please replace it with:
$import_associations = Toolset_Singleton_Factory::get( '\OTGS\Toolset\Types\Post\Import\Associations',
Toolset_Singleton_Factory::get( '\OTGS\Toolset\Types\Post\Meta\Associations' ),
Toolset_Singleton_Factory::get( '\OTGS\Toolset\Types\Wordpress\Post\Storage', $wpdb ),
Toolset_Singleton_Factory::get( '\OTGS\Toolset\Types\Wordpress\Postmeta\Storage', $wpdb ),
Toolset_Relationship_Definition_Repository::get_instance(),
$association_repository,
Toolset_Singleton_Factory::get( '\OTGS\Toolset\Types\Post\Import\Association\Factory' ),
Toolset_Singleton_Factory::get( '\OTGS\Toolset\Common\Relationships\API\Factory' )
);
After saving the file changes, try the import of the House Search module again.
