Audacity 3.1.2 keeps crashing when trying to open file

Can anyone help?
We have a problem where a file saved in audacity 3.1.2 on MAC is now making the programme crash every time it opens.
The file was saved yesterday and no error messages came up, but now we just get the spinning wheel of death.
I see especially @jademan has helped a lot of people and wondering if you can help us too?
Should we share a link to a zipped file here?

The first thing to try is updating to Audacity 3.1.3 (
I can’t guarantee that it will fix the problem, but Audacity 3.1.3 fixes some crash bugs that were in 3.1.2.

What he said. :wink:
