Anyone else seeing BSOD issues in cldflt.sys after installing KB4517389

On my laptop machine (but not on my desktop) I started getting BSOD failures in cldflt.sys after installing KB4517389. Symptoms basically the same as those reported in

https://answers.microsoft.com/en-us/windows/forum/all/onedrives-cldfltsys-causing-ntfssys-bsod/d2ef7f16-9e45-406f-95ca-6e595271e6d9?page=1

Uninstalling KB4517389 fixes the problem. Presumably, disabling cldflt.sys would do so, too, but I haven't tried that yet.

    Report this to Microsoft so that this issue can be fixed in future updates. Press Windows Key+F to invoke Feedback Hub to send the issue to Microsoft.

    Since the issue has been caused due to recent Windows update - I would suggest that you uninstall the latest KB update and hide it so that it doesn't install it automatically and wait for new update to come which will be installed automatically.

    Microsoft has provided a tool Show/Hide Updates tool to block the update

    Download the tool from below link

    http://download.microsoft.com/download/f/2/2/f2...

    When you run this troubleshooter, it will search for available updates and list them

    Select the update which you want to hide. Click Next and follow on-screen directions

    Thanks, Vijay. However:

    1. As far as I can see that file is not installed on my system; and
    2. SetupRST.exe tells me that my platform is not supported.

    Since installing KB4517389 makes the error occur, and removing it solves the error, isn't it more likely to be an issue with that update?
