I previewed a project, and closed Godot by closing the command CLI window instead of first stopping the preview and then quitting Godot.

Now every time I open Godot it runs the preview of the last project, and I can't seem to return to the IDE - I tried deleting all the preferences in the user directory, but for some reason it keeps opening the last project and runs it in preview mode, with no (obvious) way to return to the IDE.

So my question: how do I open the IDE, and prevent the game from running automatically?

System: Windows 10

I solved it just now. I deleted the pack file that I had compiled, and the project manager pulls up again. What a relief.

Still, this is a really silly bug.

That's definitely a bug. You should report it on the github if you haven't already.

6 days later

I figured it out: I had compiled a Windows binary, and saved it and the the data.pck on my desktop - which is where I have Godot saved. It seems when a data.pck is present in the same location as Godot, that data.pck file will be opened and run automatically by Godot.

I think this is by design.
