v3.1.0 beta cannot open project made with 3.0.4

Hi, I created a project with V3.0, and still can open it with 3.0.4.
But I cannot open it with v3.1.

When trying to open with 3.1.0.beta I have the following error message: (rather a warning)
“You are opening an older project (version 3.0.x)
When you save, it will be upgraded and will not be readable by version 3.0.4.”

When going ahead (“Continue”) I get the following error:
“AttributeError: ‘NoneType’ object has no attribute ‘isTemporary’”

I am using MacBook Pro, OSX 11.6.1, M1 chip.
Here is the output in the shell:

Hi Paul,
Thanks for reporting this; sorry this happened.
It would be useful for us to if you:

  • Save it in 3.0.4 (Project → SaveAs, chose a new name) and load that in 3.1.0 and see if that works.
  • Sent the project (zip/tar) in question to Ed (ejb66@leicester.ac.uk) and myself (gv29@leicester.ac.uk), so we can look into it.

Cheers,
Geerten
