Failure when loading experiment

Dear all,
I am creating a experiment in psychopy (version 1.84.1, Mac), and when I try to load it after saving I always get an error message, and the layout in builder gets blank.

I saw a similar problem reported here in the forum some days ago (Failure to load PsychoPy experiment), which was due to not saving/loading the experiment using the proper extensions. I tryed to check whether my problem would be the same but it didint find anything (just using very basic “save as” and then "save"in the builder version)

Here is the message I am getting:
Welcome to PsychoPy2!
