SQL query is running, but stopped producing incremental results - sql-server

Question

I have the below query running in SQL Server. In a nutshell, I have 3 somewhat identical queries "unioned". When I start the query, it runs and produces incremental results in the Results pane. But, once it reaches 264,619 records (first 5 minutes), it just stops producing results, yet the query is running and has been running for 30 minutes. Any ideas why this is happening? I understand the query below is kind of long/semi-complex, so my apologies, I couldn't make it any simpler (I'm hoping someone might be able to point me in a direction that I would be able to make the query below a little simpler). Below the query is a screenshot of the results pane. I'm wondering if the query is deadlocked somewhere or running into an infinite loop/etc.:

Answer 1

Without the table definitions I can't verify that this is correct, but this would be my take at a simplification of the above, with an assumption about two fixes in the join conditions:
set transaction isolation level read uncommitted;
WITH JobIDs AS
(
select j.fkJobId from tblJobs_Lists j
inner join customobject c on j.customobjectid = c.customobjectid
