Folks!! IF, you have seen or are experiencing this error message with the latest Patch Tuesday update KB5034441, the professional advice across the board is!! LEAVE IT AS IS, WAIT FOR MICROSOFT to correct their issue. The command line suggestions offered by Microsoft DO NOT WORK. In a nutshell, don't bork your systems by letting this spook you. The issue this corrects requires "local access" to a device to deploy in the first place. Just wait this one out. Its totally on Microsoft.
