Bug ID: 50026
           Summary: Powershell Core errors (in win10 mode) with:
                    Attempting to perform the Start operation on the
                    'FileSystem' provider failed. Unable to find an entry
                    point named
                    'RtlQueryProcessPlaceholderCompatibilityMode' in DLL
                    'ntd ll.dll'.
           Product: Wine

patch with stub
This happens on every command if win10 version is set, i.e.
wine pwsh.exe -c Write-Host "Hello"
Attempting to perform the Start operation on the 'FileSystem' provider failed.
Unable to find an entry point named
'RtlQueryProcessPlaceholderCompatibilityMode' in DLL 'ntdll.dll'.
Though it continues happily further and the command(s) work, this actually
prevents Waves Central from starting in win10 mode
I`ll send attached patch (that fixes this) later.
Relevant code from Powershell Core:
#if !UNIX
            // The placeholder mode management APIs
Rtl(Set|Query)(Process|Thread)PlaceholderCompatibilityMode
            // are only supported starting with Windows 10 version 1803 (build
17134)
            Version minBuildForPlaceHolderAPIs = new Version(10, 0, 17134, 0);
            if (Environment.OSVersion.Version >= minBuildForPlaceHolderAPIs)
            {
                // let's be safe, don't change the PlaceHolderCompatibilityMode
if the current one is not what we expect
                if (NativeMethods.PHCM_DISGUISE_PLACEHOLDER ==
NativeMethods.RtlQueryProcessPlaceholderCompatibilityMode())
                {
NativeMethods.RtlSetProcessPlaceholderCompatibilityMode(NativeMethods.PHCM_EXPOSE_PLACEHOLDERS);
                }
            }
#endif
