PublishSingleFile=true causes maui app to crash at launch

[MaxWang-MS]

Description

Trying to set the PublishSingleFile to true during publishing causes maui apps to crash at launch on Windows.

Also using dotnet --version it seems that I am on 6.0.400, which according to the version selection dropdown on the issue creation page is not the latest version. But I just updated VS to 17.3 GA today and freshly installed maui from that installer, so I don't know why I am not "up-to-date". Additionally, I am confused whether .net version and "maui version" are the same (i.e. always in sync). If not how do I know the version of maui on my machine?

Deploying unpackaged exe on Windows also has other issues, please refer to #6202 for details.

Steps to Reproduce

1. dotnet new maui
2. dotnet publish -f net6.0-windows10.0.19041.0 -c Release -p:WindowsPackageType=None -p:PublishSingleFile=true
3. run bin\Release\net6.0-windows10.0.19041.0\win10-x64\publish\NAMEOFAPP.exe
4. Observe crash

create a (full) memory dump with the help of Windows Error reporting service and analyze it with Windbg + pde.dll
