WebView2 WPF application could not be loaded on second desktop created programmatically. ( Both on standard and Admin privilege's)

I want to load WPF WebView2 browser in new desktop created programmatically.
Later, I have reproduced the issue with WebView2 WPF sample application(WebView2WpfBrowser).
Application is started, but WebView2 control not loaded. Exception captured seems 0x80070578

Install-Package Microsoft.Web.WebView2 -Version 0.9.538
Could you check this issue..?

HDESK hOriginalDesk=::GetThreadDesktop(dwThreadId);
if (0==hOriginalDesk)
{
return false;
}

HDESK hUserDesktop = ::CreateDesktopA( "DesktopB",
	0,
	0,

if (0==hUserDesktop )

}


Sleep(5000);
if (!::SwitchDesktop(hUserDesktop))
{
	Sleep(30000);
	::SwitchDesktop(hOriginalDesk);
	return false;
}
CreateChildProcess();
Sleep(30000);
::SwitchDesktop(hOriginalDesk);

}

ZeroMemory(&siStartInfo, sizeof(STARTUPINFO));
siStartInfo.cb = sizeof(STARTUPINFO);
siStartInfo.lpDesktop = (char*)"DesktopB";

// Create the child process. 

bSuccess = CreateProcessA(NULL,
	szCmdline,     // command line 
	NULL,          // process security attributes 
	NULL,          // primary thread security attributes

	0,             // creation flags 
	NULL,          // use parent's environment 
	NULL,          // use parent's current directory 
	&siStartInfo,  // STARTUPINFO pointer 
	&piProcInfo);  // receives PROCESS_INFORMATION 

 // If an error occurs, exit the application. 
if (!bSuccess)
{
}
else
{
	// Close handles to the child process and its primary thread.
	// Some applications might keep these handles to monitor the status
	// of the child process, for example. 

	CloseHandle(piProcInfo.hProcess);
	CloseHandle(piProcInfo.hThread);

	// Close handles to the stdin and stdout pipes no longer needed by the child process.
	// If they are not explicitly closed, there is no way to recognize that the child process has ended.

}

}

// Please change szCmdline with exact path of WPF application.

Start with the supplied CreateDesktopA and CreateProcessA reproduction and the WebView2WpfBrowser sample, using the second desktop setup and exception 0x80070578 as the initial checkpoints. Confirm whether the WebView2 control consistently fails to load there, then document a confirmed resolution or limitation for this scenario.
