On October 2, Microsoft made available the newest feature update to Windows 10 1809, called the October update version 1809 to download and install for new users. The update initially in seeker only mode, was released to production as well as Release preview ring Insiders. One could either do an Inplace Upgrade or Download ISO File. The rollout on the first day went smoothly with minor bugs being reported.
As the people who started download increased, reports started to come that files were being lost after the update. As files are one of the most important things for a user, Microsoft has decided to halt the upgrade process until further notice. The Windows 10 update History page explains the same:
|We have paused the rollout of the Windows 10 October 2018 Update (version 1809) for all users as we investigate isolated reports of users missing some files after updating.||

We will provide an update when we resume rolling out the Windows 10 October 2018 Update to customers.
The Software download page Media creation tool has been replaced with version 1803 and Update assistant shows no updates are available, at the time of writing.
If you are affected
Microsoft says if you are affected, you can do a rollback of version 1803(However, no guarantees your files would be back). For more help, you can contact Microsoft as well.
I would update this article if there is an update.
