Problem is the & in the step file.
Workaround: Remove it, open it, Save the project and it works.

Even if it the step file is the root cause, I think the slicer should still be able to reopen the project again, especially since it was able to create the project and print it and save it without issues or errors. Why does it treat it differently when opening it later on? Also would be useful for the rest of the models in the project to still load up, rather than the whole project fail to open.

Good question, that must answer us a programmer.

Maybe @DokuKaefer is right. But this shoud be fixed in the 1.7 version. We'll check it again.

I can't seem to find the & in the .step file when opening it with VS Code. Can you show me where it is?

the & in the filename of the step file is the problem.
Rename it like inner_outer.step

[RyanEwen]

Ah I see. Looks like if I just rename it within the slicer by hitting F2 on it, that works as well.

Thank you!

It has been fixed in the latest version.
If you use the new version of the software to save the model file with & in the name, it can be opened normally with the new version.
