-SQL Server 2019 CU14 introduced a [fix to address wrong results in parallel plans returned by the built-in SESSION_CONTEXT](https://support.microsoft.com/help/5008114). However, this fix might create access violation dump files when the SESSION is reset for reuse. To mitigate this issue and avoid incorrect results, you can disable the original fix, and also disable the parallelism for the built-in `SESSION_CONTEXT`. To do this, use the following trace flags:
-
-- 11042 - This trace flag disables the parallelism for the built-in `SESSION_CONTEXT`.
-
-- 9432 - This trace flag disables the fix that was introduced in SQL Server 2019 CU14.

-SQL Server 2019 CU 27 introduced fix [2994446](../sqlserver-2019/cumulativeupdate27.md#2994446) to make secondary databases in an availability group (AG) startup more reliably. However, this fix causes a problem where AG databases don't start recovery if SQL Server is running in single-user mode. SQL Server Setup runs in single-user mode. As a result of this, if you run Setup and also have SQL replication, change data capture (CDC), or SQL Server Integration Services database (**SSISDB**) enabled on a database in the AG, when the catalog upgrade scripts try to run but can't access the database, setup fails.

 The issue arises from a code change in SQL Server 2022 CU14 that checks if a database is online and ready to be frozen. The current solution is to roll back to SQL Server 2022 CU13 and perform the snapshot backup.
