Hello, A pleasure to help you.
I must tell you that the problem that occurs after the update is known and the Microsoft team is in the process of investigation, since several users have reported this incident.
"We have paused the implementation of the Windows Update October 10, 2018 (version 1809) for all users while investigating isolated user reports that are missing some files after the update.
Microsoft employs a gradual implementation scheme, and not all Windows 10 users have received their last six-month update of the operating system. "

They suggested that you follow the Workaround steps that Microsoft requests to know about your incident described in the previous article.
Please let me know if the information was useful or if you need to continue with my support.
