Update to wordpress 6.1 failed

Hi

I attempted to do a manual update to 6.1 using this page as a guide:

Updating WordPress

When I manually move the contents of the wp-includes folder it breaks the database connection (or so it appears):
“This either means that the username and password information in your wp-config.php file is incorrect or that contact with the database server at xxxxxxxxx could not be established. This could mean your host’s database server is down.”
This happens when I move over the new link-template.php file into the existing wp-includes folder.

When I looked at the php-error.log I see this:

WordPress database error [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Invalid object name 'wp_spectrom_sync_log'. Code - 208 for query SELECT COUNT(*) as Computed

Also, I do not have the automatic update button available when I use the wp-admin dashboard so the update has to be done manually,

Any ideas why this is happening?

Thanks!
