start_license "meba" showing blank when app starts

```
from ansys.mechanical.core import App
app=App(globals=globals(), start_license="meba")
print(app)

Ansys Mechanical []
Product Version:
Software build date:
```

Reproduce the reported startup behavior using the App entry point with globals=globals() and start_license="meba". Trace how the selected license affects startup and the App string output; done means the printed Ansys Mechanical details include the expected product version and software build date.
