Job execution status run check never completes

Question

I have a process where I check for SQL Server agent job execution status making sure all the jobs in question have their last run for the given date completed reporting either success or failure. Based on the outcome of the last run I either execute downstream jobs on success or abort on failure. I have this process which waits for a minute and then loops through all the specified jobs until all are complete.

The problem I run into is when I investigate the job activity monitor I see all the jobs complete either reporting success or failure. But, my query does not complete. Its stuck in this infinite loop.

Is there any better approach than what I'm already doing to address this.

SQL:

BEGIN

    DECLARE @noofjob INT;
    DECLARE @failedjob VARCHAR(MAX);
    DECLARE @jobnames TABLE (name VARCHAR(255)); -- To store job names
    DECLARE @jobname VARCHAR(MAX) = 'child_job_1,child_job_2,child_job_3,child_job_4,child_job_5';

    -- Copy SQL Agent job history into a temp table
        SELECT  jh.[instance_id],
        jh.[job_id],
        j.[name],
        j.[description],
        jh.[step_id],
        jh.[step_name],
        jh.[sql_message_id],
        jh.[sql_severity],
        jh.[message],
        jh.[run_status],
        CASE WHEN jh.[run_status] = 1 THEN 'Succeeded'
             WHEN jh.[run_status] = 0 THEN 'Failed'
             WHEN jh.[run_status] = 2 THEN 'Canceled'
             ELSE 'Unknown'
         END AS [run_status_description],
        jh.[run_date],
        jh.[run_time],
        msdb.dbo.agent_datetime(jh.run_date, jh.run_time) AS 'run_date_time',
        jh.[run_duration],
        jh.[operator_id_emailed],
        jh.[operator_id_netsent],
        jh.[operator_id_paged],
        jh.[retries_attempted],
        jh.[server]
   INTO #jobhistory
   FROM [msdb].[dbo].[sysjobhistory] jh
   JOIN [msdb].[dbo].[sysjobs] j 
     ON j.[job_id] = jh.[job_id]
    
    -- Insert job names into table variable
    INSERT INTO @jobnames(name)
    SELECT value FROM STRING_SPLIT(@jobname, ',');

    -- Count number of distinct jobs
    SELECT @noofjob = COUNT(*) FROM @jobnames;

    WHILE 1 = 1
    BEGIN
        -- Drop temp table if it exists
        DROP TABLE IF EXISTS #lastrun;

        SELECT name, MAX(run_date_time) AS latest_run
        INTO #lastrun
        FROM #jobhistory
        WHERE run_date_time > CAST(GETDATE() AS DATE)
        AND name IN (SELECT name FROM @jobnames)
        GROUP BY name;

        -- Check if all jobs have run in the last 6 hours
        IF @noofjob != (
            SELECT COUNT(DISTINCT name)
            FROM #jobhistory
            WHERE run_date_time > DATEADD(HOUR, -6, GETDATE())
            AND name IN (SELECT name FROM @jobnames)
        )
        BEGIN

                    FROM #jobhistory S

                        AND S.run_date_time = lr.latest_run
                    WHERE S.run_status != 1 -- '1' denotes success
                ) AS FailedJobs
            );

            -- Check if there are any failed jobs
            IF LEN(@failedjob) > 0
