Thanks for reporting the issue. I am creating an internal work item to return E_INVALIDARG in this case, which should be a better error code to return.

Specifying size of 0 for shared buffer is not supported and we currently returns E_OUTOFMEMORY when that is specified. I assume that you are not really trying to share a 0 sized buffer, right?

A fixed has been made that returns E_INVALIDARG when 0 buffer size is specified. It will be in Edge WebView2 Runtime version 126 to be released in about a month.
