Does the antivirus software you use have a CLI?

You could write a script task in C#, VB.Net to interact with your AV and call it to scan the file...

That is not easy! This gets you part of the way, but the MultiValue bit is missing:

DROP TABLE IF EXISTS #XML_TABLE;

CREATE TABLE #XML_TABLE

It's difficult to help without seeing the actual execution plan and the DDL for StockDB (assuming that is a table rather than a database!)

For a quick fix, try the divide...

The database was working on copy (SQL server 2008) and now it is not working  on copy (SQL server 2014) and I get error number (0xc0202009)

Here is a version with a sequence number which you should be able to adapt

DROP TABLE IF EXISTS #Leave;

CREATE TABLE #Leave

The sample data you have provided has no column which provides ordering. Without a column to order by, a T-SQL solution is not possible.

Compare the execution plans in both environments. Are they identical?

Are the hardware, o/s and SQL Server versions the same?

Have you checked for blocking?
