OrcaSlicer Version

2.4.0-dev

Build: c661ddc2 if this is the same as the v1.0.0 Windows release build
Installed from: OrcaSlicer_Windows_Installer_V2.4.0-dev.exe

Printer(version)

Bambu Lab X1 Carbon(1.11.02.00)

Bambu Network Plug-in Version

02.05.02.58

Description

OrcaSlicer-bambulab launches and initially connects to my Bambu Lab X1 Carbon correctly.
At first, the printer status and temperatures are displayed normally.

However, when I open the camera stream from the Device tab, OrcaSlicer immediately crashes/closes.
After that, all Bambu printers become inaccessible from OrcaSlicer until the app is restarted.

I also noticed that the application can crash when doing relatively light UI/load-heavy operations, not only when opening the camera.

Bambu Studio works normally on the same PC with the same printer, including camera access, so this does not appear to be a printer, network, or account issue.

Additional notes

Files attached

I will attach the OrcaSlicer logs and Windows Event Viewer crash details if needed.

How to reproduce

1. Install OrcaSlicer-bambulab 2.4.0-dev on Windows 11.
2. Install Bambu Network Plug-in 02.05.02.58.
3. Log in to Bambu account.
4. Add or open a Bambu Lab X1 Carbon.
5. Open the Device tab.
6. Confirm that temperatures and printer status appear normally.
7. Click the camera/play button.
8. OrcaSlicer immediately crashes/closes!

Actual results

OrcaSlicer closes/crashes immediately when the camera stream is started.
Sometimes the app also crashes under light UI/load operations.

Expected results

The camera stream should open normally, or at least fail gracefully without crashing the whole application.

Project file & Debug log uploads

No project file is involved because this crash happens in the Device tab when enabling the Bambu camera, before opening or slicing any model.

I attached the OrcaSlicer log files and Windows Event Viewer crash information instead.

Checklist of files to include

• Log file
• Project file

Anything else?

Bambu Studio works normally on the same Windows 11 PC.
The same X1 Carbon camera stream works correctly in Bambu Studio.
Reinstalling the Bambu Network Plug-in did not fix the problem.
