Wordpress theme development : Call to undefined function WP_Query()

I'm developing my own Wordpress theme and I have this issue "Call to undefined function WP_Query()" with my functions.php file while trying to get my Custom posts ("event").

I already tried to add include('wp-load.php') but did not change anything.

Did anyone already have the same issue ?
Already did some researches but did not find anything that solved my problem.

Here is my simple code :

$argsEvents = array('post_type' => 'event', 'posts_per_page' => '-1');

$result = WP_Query( $argsEvents );

if ( $result->have_posts() ) {

echo '<ul>';
while ( $result->have_posts() ) {

$result->the_post();

echo '<li>' . get_the_title() . '</li>';
}
echo '</ul>';

wp_reset_postdata();

} else echo "No data";


Thanks a lot for you help!

You should be using new before calling WP_Query.

Change:

$result = WP_Query( $argsEvents );

To:

$result = new WP_Query( $argsEvents );
