Upgrade to 1.42.1 Error

I am upgrading to version 1.42.1 and am getting the following error:

...cargo_tables_template_id key doesn't exist.
Running 
D:\...\extensions\OATHAuth/maintenance/updateTOTPScratchTokensToArray.php...

An error occurred:
Error 1044: Access denied for user 'db_username'@'%' to database 'virtual'
Function: Wikimedia\Rdbms\DatabaseMySQL::doSelectDomain
Query: USE `virtual`


Notes:

$wgDBuser = is _not_ in the form of an email address ([email protected])

db_username (above is a replacement for the actual db username).


Any ideas on how to overcome this?
