Create Virtual Desktop: A_LastError: 14007

Disclaimer: It could be that my Windows is broken - see https://aka.ms/AAmdzjq

I try to create a virtual desktop using a short AHK script:

VDA_PATH := A_ScriptDir . "\VirtualDesktopAccessor.dll"
hVirtualDesktopAccessor := DllCall("LoadLibrary", "Str", VDA_PATH, "Ptr")
CreateDesktopProc := DllCall("GetProcAddress", "Ptr", hVirtualDesktopAccessor, "AStr", "CreateDesktop", "Ptr")

CreateDesktop() {
    global CreateDesktopProc
    try {
        ran := DllCall(CreateDesktopProc)
        if (ErrorLevel = "FAIL") {
            MsgBox % "DllCall failed with ErrorLevel: " ErrorLevel
            return
        }
        if (A_LastError != 0) {
            MsgBox % "A_LastError: " A_LastError
            return
        }
        MsgBox % "Return value: " ran
    } catch e {
        MsgBox % "Exception: " e.Message
    }
    return ran
}

CreateDesktop()

I get A_LastError: 14007 when executing.

Does this happen for everyone - or just for me?

Did you try with the latest Windows 11 binary? To me whole DLL stopped functioning on 31st of August, and I released a new binary 2 days ago.

Latest binary works only with at least 22621.2215, start winver.exe, and see what your version is.

My unit/integration test shows that create desktop should function:

running 1 test
Retry the function after ComNotInitialized
test tests::test_create_desktop ... ok
