Okey dokey, I got curious and typed out that xml link from the console pic because I wondered why a forum link was in there. I think Iβve typed it correctly and here it is: https://forum.gdevelop.io/message-bus/ac86bd574e594bf68bf7fdc063e39cbd/poll
It goes to a virtually empty page apart from a few of these [ ]. Have you tried disabling different sets of your events to see if the preview will run? Do you have links in your game?
Until someone who can interpret the console errors comes along, I suggest you disable some of your events. I see you have quite a few scenes. You can disable events by right clicking/long pressing or typing D on the keyboard.
Go through and disable some, try preview, if it doesnβt work, disable some more. If any of your events are in groups it will make it easier.
If your preview works then check the most recent events you disabled. If you donβt see an obvious problem then show a screenshot here and someone will be able to figure it out. Good luck!
