Research direction

Start with the WebView2Samples build configuration for SampleApps/WebView2APISample and the HostObjectSample.idl file named in the error. Reproduce the rebuild using the Windows SDK version shown in the log, then inspect the MIDL errors for the duplicate _FLAGGED_WORD_BLOB and IUnknown definitions. Done means the project rebuilds without these errors.
