So I recently switched my project over to Godot 4 for the new TileMaps capabilities and I have been working in the new version for little less than two weeks now, but since yesterday (as of writhing this question) my main project doesn't open for some reason. My other projects open just fine as they should, It's just the main current one. When I try to open It, It loads the Godot's splash screen, freezes and says "not responding" at the top of the window next to the project's name. Although I did manage to open my project once yesterday by deleting a node directly from a scene file by opening the scene in a text editor, but when I tried the same trick today, It didn't work. Does anyone know how to fix this problem or why is it happening?

For some context: I am working on Windows 10 and coding my project in C# if such things matters in this problem.

I have the same issue on an upgraded project. I don't know the solution.

Hey, I think I figured out how to open the project. Basically when you press edit on the project and the project window opens, you have to start furiously clicking on the window screen before the splash screen comes on. It should freeze at first but then the splash screen comes on and then It loads up the project perfectly fine. It's not a best solution but a way to deal with It and at least It works. All thou I don't know why It works and why only that particular project has that kind of trouble. Hope this helps.

    Well… if the solution works, then that means no matter how weird and mystical it might be, it's… works. 🙏

      Sounds like something to report to the engine developers. Without a reproduction project I think an issue tracker ticket might get closed, but getting on the developers live chat and asking them there how to proceed debugging it might be the way to go.

        I made an account just to respond:
        If you made a script with @tool at the start, then maybe that script prevents the editor from opening. Luckily, you can easily go to where your game files are stored, and manually remove @tool at the start. This worked at least for me.
