PHP Notice: Function wpdb::prepare was called incorrectly.

Hi,

This is seen during a fresh install

When installing this plugin with debug.log enabled, it triggers a notice
[05-Mar-2024 14:40:42 UTC] PHP Notice: Function wpdb::prepare was called incorrectly. The query argument of wpdb::prepare() must have a placeholder. Please see Debugging in WordPress for more information. (This message was added in version 3.9.0.) in [path]\wp-includes\functions.php on line 6031

Additional digging seems to point to

[path]\wp-content\plugins\classified-listing\app\Database\Migrations\Forms.php

Line 39 onwards

		// Create new form if table is empty
		if ( $wpdb->get_var( "SHOW TABLES LIKE '$table'" ) ) {
			$row = $wpdb->get_var( $wpdb->prepare( "SELECT COUNT(*) from $table" ) );
			if ( ! $row ) {
				$formData = FormPreDefined::sample();
				Form::query()->insert( $formData );
			}
		}
	}
}

Please check and guide.

Thanks
