Hello
Thank you for posting in Q&A forum.
This error means that Windows Update could not find the required file.
It is one of the many errors that can potentially be fixed by the System Update Readiness tool. This tool typically runs automatically the next time you perform a Windows update when you have one of these errors. You can also download the tool from the Microsoft Download Center and run it manually to see if that fixes the error.
For information about how to download the System Update Readiness tool and what errors it can fix, see the following support article:

I hope the information above is helpful.
Best regards
Zunhui
