How to reproduce

Steps to Reproduce:

1. Launch Bambu Studio 2.2.0.2 on Windows 11.

2. Load any model file (STL or 3MF — happens with multiple projects).

3. Click the Filament/AMS Mapping button.

4. The program crashes immediately to desktop (no error dialog shown).

Note: This crash happens before slicing — I never reach the Slice button.

Actual results

As soon as I click the Filament/AMS Mapping button, Bambu Studio 2.2.0.2 immediately crashes to desktop with no error message or dialog.

The application closes completely, forcing me to restart.

This happens every time, regardless of which model (STL/3MF) is loaded.

Expected results

Clicking the Filament/AMS Mapping button should open the filament mapping dialog normally.

I should be able to remap filaments/AMS slots and continue to slice and send the model to the printer without the application closing.
