Anything else?

Wasn't sure if I should add to #10734 as I am on a different OS and had slightly different issue without having multiple instances of different version of OrcaSlicer.

Does not happens with 3MF saved on 2.3.0

Can open 3MF as project, receive this warning:

Can say yes or no and project still opens successfully, receive warning that precise wall will be ignored for outer-inner or inner-outer-inner wall sequences, which is expected but might have something to do with trying to import the 3MF instead of opening it as a project.
