Error calling procedure in MySQL: Error Code: 2013. Lost connection to MySQL server during query

I need help on MySQL, when I call a specific procedure the Workbench lose connection and the MySQL80 Windows service is arrested!

I already tried to set higher parameter (600) on Edit -> Preferences -> SQL Editor -> DBMS connection read time out (in seconds).

I don't know if it can help but here is my procedure:

DELIMITER //

DROP PROCEDURE IF EXISTS drop_unfinished //

CREATE PROCEDURE drop_unfinished(
        OUT p_return    INT,
        IN  p_forum_id  INT
    ) 
    COMMENT 'Drops all unscraped batches for the given forum'
    READS SQL DATA
BEGIN
    DECLARE v_limit INT; 
    DECLARE v_offset INT; 
    DECLARE v_scraped_batches INT;
    DECLARE v_scraped_topics INT;
    DECLARE v_edit_time DATETIME;
    DECLARE v_start_time DATETIME;
    DECLARE EXIT HANDLER FOR SQLEXCEPTION SET p_return = -1; 

    SELECT scraped_topics, scraped_batches, edit_time
    INTO v_scraped_topics, v_scraped_batches, v_edit_time
    FROM dashboard_view
    WHERE forum_id = p_forum_id;

    SET v_limit = 25;
    SET v_offset = IF(v_scraped_batches = 1, 0, v_limit * v_scraped_batches);

    CREATE TEMPORARY TABLE 
    IF NOT EXISTS topic_ids
    SELECT topic_id 
    FROM topics 
    WHERE edit_time > v_edit_time 
    LIMIT v_scraped_topics 
    OFFSET v_offset;

    DELETE FROM logs 
    WHERE step_time > v_edit_time
    AND parent_id = p_forum_id
    AND object_id IN (SELECT topic_id FROM topic_ids);

    DELETE FROM torrents_tmp 
    WHERE forum_id = p_forum_id
    AND topic_id IN (SELECT topic_id FROM topic_ids);

    DELETE FROM ed2k_links_tmp 
    WHERE forum_id = p_forum_id
    AND topic_id IN (SELECT topic_id FROM topic_ids);

    DELETE FROM posts_tmp 
    WHERE forum_id = p_forum_id
    AND topic_id IN (SELECT topic_id FROM topic_ids);

    COMMIT;

    DROP TEMPORARY TABLE topic_ids;

    SET p_return = 0;
END
//

DELIMITER ;

If I call all the queries separately (obviously with same parameters) I don't have any problem!

Suggestions to consider for your my.ini [mysqld] section

read_rnd_buffer_size=256K  # from 1 - pretty astounding you run at all
read_buffer_size=128K  # from 8K - for a more reasonable limit
thread_cache_size=40  # from 10 to prepare for growth
innodb_io_capacity=1600  # from 200 to allow higher IOPS
max_connections=50  # from default of 151 until you have more activity
innodb_buffer_pool_size=256M  # from 8M likely you will get to innodb tables soon

These changes are necessary to achieve stability for your instance.

Reviewing your PROCEDURE, will try to comment on your procedure by Friday afternoon. Some of the requested data is only available on Linux systems. To determine RAM on your machine, right clk on Window icon in left of Task Bar, clk System and you should see how much RAM is on your server.
