Error while installing cumulative update

Question

I am installing Cumulative Update Package 15 for SQL Server 2019 - KB5008996 since it seems there 's a known issue that causes my sql server polybase log to fill the harddisk
While installing I keep having operation failed , and looking at the logs I found this error :

Error: 18456, Severity: 14, State: 5.
Login failed for user 'NT Service\SSISScaleOutMaster150'. Reason: Could not find a login matching the name provided. [CLIENT: <local machine>]

I tried to add the user NT Service\SSISScaleOutMaster150 to my sql server bu tht error keeps popping up ....
Whats wrong ??
An update which should fix a problem, that instead causes another problem... nice ....

Hi @leo del ciello ,

It about Integration Services (SSIS) Scale Out
Please open SSMS, connect to this instance, right-click on logins, and then New login to add it to SQL Server login.
The default configuration does not add this account to login automatically
