SQL Server 2017 - CU19 - Curroption of Tabular SSAS Db's

Question

We've recently applied CU19 to our SSAS Dev server and immediately had db corruption errors on instance start-up.

Event Viewer showing errors such as: Errors in the metadata manager. An error occurred when loading the '<>' cube, from the file, '\<>.xml'.

SSMS showing corrupt DB warnings when loading up the instance.

We uninstalled the update and things returned to normal.

Anyone else come across this ? Is it one to go back to Microsoft with ?

Regards,

David
