Infinite GraphWindow.Repaint loading

Hello, I think I tried everything suggested in similar threads, but I can’t find a solution. I’m trying visual scripting for the first time on a Unity 6.0 very simple game (it’s all UI and a state machine). It all works well but, on a very specific graph, each time I wanted to modify anything I got stuck with longer and longer wait times while waiting for “unity code in unityeditor.coremodule.dll to finish executing”. Now, it’s at a point where I can’t even open it (it’s the ‘Start’ in the image). The rest of the graphs and -weirdly- the game itself runs flawlessly but I’m out of ideas. Could you help me?
