Normal themes on High Contrast mode on Edge 138+

Hello.

How do I disable the high contrast theme in Edge 138+? but not disable on Windows 10/11. I currently have the official build 140. I managed to disable high contrast for websites, but the Edge GUI is still completely white and gray. Before build 138, it was possible to change the theme, but since build 138, it's not possible? Is this Google's or Microsoft's idea? and how to fix it? because I want to install classic theme from Edge/Chrome store.
