Can not save project file after slicing failure

[VeloSteve]

Cura Version

5.6.0

Operating System

Windows 11 Pro

Printer

Elegoo Neptune 3 Pro

Reproduction steps

1. Open Cura 5.6.0 with no object.
2. Save project file. No problem.
3. Load an object.
4. Save project file. No problem.
5. Attempt to slice the object. That fails (reported separately).
6. Attempt to save project file for the bug report.
7. Save Project fails with 'time' as the only text in the error box below the word Error.

Actual results

The first two project files exist. The one after the slice failure was not created.

Expected results

There should be 3 project files reflecting the different steps of the process. Of course I used a different name each time.
