Changed language in yarn settings, now it always freezes

Here’s what I did: on an open dialogue tree with yarn I went to File on the top left and Settings and changed the language setting to Italian, the window immediately froze.
I could close the window and use the rest of gdevelop just fine but every time I try to edit the dialogue with Yarn it freezes immediately after opening, on any project.
Is there any way to reset that setting manually by changing a file or something?
