Thunkable designer website is Blank

My Thunkable x projects are showing, however, when I’m clicking on a project to edit it, it isn’t showing anything. Just a Blank Page.

Link to project: https://x.thunkable.com/projects/5d26c0051f02a2c15b2d077a/openProject/designer
on clicking “copy” it is showing this bizarre error.

Were you able to open the project?
