I recently updated Windows 10 to version 2004, and after the last update-related reboot OneDrive would keep complaining about not being able to connect to Windows--required for the Files On-Demand feature (see snapshot below).
I tried both workarounds related to cldflt.sys described in this Support article, but in my case both were checking out fine. I finally gave in & clicked Download Files, which was supposed to disable Files On-Demand and just pull down everything that wasn't there already. But the sync gets stuck immediately, claiming that it's downloading 1 out of 35 files (18MB total), except no matter how long I leave it, or how many times I restart OneDrive or logout & back in or restart the entire machine, it never moves forward...
To make matters worse, none of the files synced to OneDrive now open; I am using OneDrive to backup Desktop, Documents, and Pictures, so none of those files can be opened... Here is an example of a message thrown when trying to open a PDF on my Desktop (which, by the way, is fully sync'ed, as indicated by the green check overlay on the file's icon):
Any ideas how to get out of this pickle?

This fix worked for me as well. My OneDrive Personal and OneDrive Business both were not syncing after the upgrade. This registry change did the trick. Nice sleuthing on that. Also, thanks to the OP for providing a very clear write up and description of the issue.

I hope somebody from Microsoft with at least a little bit of competence can address this issue.
Microsoft constantly drops the ball on its Windows 10 updates and could care less about consumers or small businesses.
I'm about ready to drop Windows altogether and switch to the only crap option of Linux, in addition to my personal and business subscriptions of Office 365 since it seems impossible to have a reliable computer with MS's poor customer support.
Call their customer service for any reason or chat with them in a chat and you're bound to get the most incompetent of people. The corporation as a whole doesn't care about its consumers because they have a contract with nearly every government agency in the US as well as the larger enterprises.

@MStruzak I'm also having this issue after the install of 2004. It's effectively killed most of the files stored in my local OneDrive folder because they no longer open or sync. I've tried all the support tips of pausing sync / unpausing, uninstalling / re-installing different versions. What a massive waste of time for so many people!

Hi, Have you tried this fix ?

Windows 10 gave me a notification saying that a troubleshooter for OneDrive needed to run. After running the troubleshooter and rebooting, I could turn on Files on Demand without the error occurring.
However…
I'm now finding that most of the time (although not always), when I right click on a file in OneDrive to change its sync mode, the context menu disappears within less than a second. This isn't happening with files outside of OneDrive.
Second, I'm finding that it now appears to be impossible to turn off Files on Demand. When I uncheck the box, a message pops up reading "Disable Files on Demand. All OneDrive files and folders will download to this PC". There are OK and cancel buttons. Regardless of which one I click on, the Files on Demand checkbox gets re-checked.

@MStruzak I just started my PC and got a notification for running a Troubleshooter to fix my OneDrive files on demand connection and sync issue. I ran it. Restarted and BANG. It all works! Thank you so much for responding to this quickly. So pleased :)

My theory is that they wanted to make our systems more "secure", but it lead to disaster, as with many other things with this update @Josep1190
