Hi Sara,
I'm Dyari. Thanks for reaching out. I will be happy to assist you in this regard.
This is a known issue. Microsoft is aware of it and working on a resolution and will provide an update in an upcoming release.
You do not need this update if the PC does not have a recovery partition. In this case, the error can be safely ignored.

However, to avoid this error or recover from this failure, please follow the instructions to manually resize your partition to install the WinRE update and then try installing this update:

Otherwise, it is best to wait until Microsoft releases a patch for it.
Please let me know if you need further assistance and keep me updated.
