Ok so first you need to have your visual studio 2019 up to date and have the sdk installed as mentioned in this link (for windows part)
make sure to have the windows 10 and 11 sdks
on that page just the part from " Fix SDK Not Setup UE5 For Packaging to Windows" not everything
then go to LyraStarterGame folder and move/delete the Intermediate folder
then open the project and select the Refresh Platform Status (is in the build menu at top of unreal)
One last thing I’ve did on top of this is to unlock the editor from the firewall, for some reason the editor was not able to go online. Not sure if this have anything to do but as last resort you can try it.
after that it worked. the game built successfully and works perfect. quite nice actually. really like it. trying to figure out what is what inside right now 
also I’ve found this link about the project
