Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.2-dev build e32dbd3

Operating System (OS)

Linux

OS Version

Debian 13

Additional system information

No response

Printer

Bambu Lab H2D / Bambu Lab X1C

How to reproduce

Open OrcaSlicer
Go to Device Tab and select X1C or H2D if not already selected
Go to Prepare Tab
Click sync printer icon
Click Continue to Sync Filaments
If UI is not yet frozen, Click Sync printer button again.

Actual results

OrcaSlicer UI and entire X11 system should become unresponsive to keyboard and mouse clicks. Does not seem to resolve on its own in a reasonable amount of time. Forced to go virtual terminal with Ctrl+Alt+FX keys to kill OracSlicer. Once killed, X11 system returns to normal.

Expected results

UI continues to work.

Anything else?

Only syncing the filaments seems to cause the problem. I can sync repeatedly and click cancel on the Sync Filaments confirmation screen a no lockup occurs.
