Hello. Thank you for contacting the Toolset support.
This looks like there is not enough permission available on your server which don't allow adding and removing custom database tables or such database related operation.
Can you please try to grant full permission on your database and check if that help you to resolve your issue.
Alternatively, you can try to deploy your website's clone to a different server (even a local host server will do) and check if you see the same error on this server.
At this new server location, you can complete the database update process, and once done, you can migrate it back to the actual server.
