This issue was resolved with an update on September 2: https://docs.microsoft.com/en-us/dynamics365/mixed-reality/guides/new#september-2-2020
Version 404.2009.2003 of the PC app and version 404.2009.2004 of the HoloLens app fixed a bug introduced in the August 25 release that prevented some guides from opening and displayed a misleading error message. You don't need to update the Dynamics 365 Guides solution to get this update.
Thank you Ryan san!
