¶ What the issue is
When editing a .3mf file in Bambu Studio on Windows operating systems, Bambu Studio occationally crashes during slicing either after switching to the Preview tab, or clicking Slice all or Slice plate.
¶ GPU Thread Optimization Issue
If your computer uses an NVIDIA GPU, its multi-threaded optimization may cause Bambu Studio to crash during the slicing process. You can disable it using the following method.
In the NVIDIA Control Panel, go to 3D Settings → Manage 3D Settings → Program Settings, and add Bambu Studio to the program list (if it’s not already there). Find the setting named Threaded Optimization and turn it Off.
If you cannot find the NVIDIA Control Panel on your computer, you can download and install it via the Microsoft Store, or update the latest drivers from the official NVIDIA website.
