"O3DE Project Launcher fails to start Editor" about o3de HOT 5 OPEN

Just for additional information here, we did some step by step trials and none of the following worked. Note that the user folder had a space in its name (which may or may not be relevant)

• Cleared out the O3DE editor and o3de regkey
• Cleared out the O3DE manifest in %USERPROFILE%\.o3de
• Used an installer version downloaded from the official website, installed into a folder without a space in its name.
• Used the o3de.exe project manager from the installer to create a new project in a folder near the root with no space in its name.
• Built without error.
• Launched editor.exe directly from the command line from the installer. It was able to start, and then invoke the project manager and shut itself down. (This proves that its able to launch and find its dlls)
• Launched editor.exe directly from the command line with the --project-path=... param. It shut down without creating logs or outputting any messages.

Note that the user's machine was previously able to run from a source-compiled O3DE. It was only after installing an installer (o3de-sdk) that it gave this trouble.

Ok editor will not start on installer when I hit the project button. So I tried something before I built the project I tried running the project before building it and it gave me a popup error then started the loading window but did not start the editor ill show u the image of the popup window but after i built the project neither the popup window or the editor poped up or any error windows any help how to fix this as i cannot start a game project.

It appears that the first error game some error logs before I built the project ill post them here.

It looks like a Nullptr dereference in the EditorViewportWidget::SetAsActiveViewport function.

An educated guess on what the problem is with the Editor start-up is that the Atom RPI is not initializing the ViewportContextRequestInterface on startup.

I wonder if there is an issue related to initialization of the Graphic system.

@stevo26 Are you able to attach the Editor.log file from <project-root>/user/Log?
