Query call in php hangs other queries

Question

Because when doing a first query to a call and then trying to do another php hangs? For example, run this stored simple file in php

DELIMITER $$
CREATE DEFINER=`root`@`localhost` PROCEDURE `curtidas_sp` (
    IN `@post` INT
)  
SELECT 
    COUNT(*) AS c_total,
FROM curtidas 
WHERE id_post = `@post`$$

DELIMITER ;

running in php:

$f_dados = mysqli_query($conexao, "CALL curtidas_sp('$idPost')");
$f_resultado = mysqli_fetch_assoc($f_dados);

And then try to run down another being or not a call

$c_dados = mysqli_query($conexao, "SELECT COUNT(*) AS f_total, FROM favoritos WHERE id_post = 2");
$c_resultado = mysqli_fetch_assoc($c_dados);

Displays this error:

mysqli_fetch_array() expects Parameter 1 to be mysqli_result, Boolean Given...
