To confirm. logon to the SQL Server that hosts the session recording database and run the below query to check the DB Schema version:
select * from dbo.schemaversion

For 1912 version, it should be 1240, whereas we see it is 1200, and this confirms that the upgrade did not complete fine.
If you see this scenario, please reach out to Citrix Technical Support for assistance.
The fix is to upgrade the DBSchema to version 1240 by running scripts on SQL database of session recording.
