i’m not skilled enough to debug this myself. please help, thanks

Hello flow!

I'm sorry for the late reply. I think you can fix the error by opening the PreviewRenderingViewport script, replacing line 18 with 

    [Export] private Godot.Environment _environment;

and then removing line 11, that says 

    using Environment = Godot.Environment; 

Don't forget to save and press the "Build" button in the top right corner of Godot afterwards.

Please let me know, if this fixed your issue. I will then include this fix in the next version accordingly.
