This code doesn't handle the case where `CoInitializeEx` returns
`RPC_E_CHANGED_MODE`. As [discussed
previously](https://github.com/openjdk/jdk/pull/14898#discussion_r1327639556),
we can proceed in this case too, but we must not call `CoUninitialize`.
It also need to be handled in the similar code below.
