Thanks for sending the screenshot - in the terminal where you started Slicer there’s a python error saying that numpy cannot be imported and that’s why the Editor didn’t load.

You’ll need to go back and debug the build process to make numpy work since a lot of Slicer code depends on it. Building numpy, especially on windows, can be tricky, but if you describe your steps and post build logs hopefully someone here can help.
