What were you doing when it crashed? (ie: open the app, load X, select Y, etc.).
From the exception code, it is a heap corruption (buffer under/overrun), and the NTDLL failed while trying to allocate or free memory.
This could be configuration or file specific, and the Bambu engineers will need a bit more information to narrow down a reproducible case.

After a print has finished and i load a new file or on-line print, it crashes. It is during the load of the second print the application crashes and disapears

Updated to 2.4.0.70 yesterday and it crashes a lot, typically when slicing though it did crash when simply loading a file.

Windows 10, AMD GPU.

Same, I updated to V2.4.0.70, not only is it resource intense (more so than prior versions) but it crashes constantly.

• Crashes whilst moving an object around on the build plate
• Crashes when slicing
• Crashes when not doing anything at all.

Windows 11

  • I have rebooted, no changes.
  • Previous version used was 2.0.3.54 and v2.1.1 - no issues, especially like this

I’ve had at least 3 crashes over the last 2 days. It’s been more over the last few weeks but that’s all the crash dumps I see in my logs folder.

All of them have the same exception code 0xc0000374 (Heap Corruption).

My guess it’s a use after free bug or something.

I’m, not 100% sure but it could be happening after the computer wakes up from sleep while Bambu studio is still running, or maybe after the second slice of the day or maybe something else completely, not sure.

Yep, mine crashes after every print. Have to retry multiple times and then eventually the print works. Happens for me while generating the gcode in preview.

There are a few instances of this happening. From total crash to the slicer “hanging” then recovering. Constant Freezing/Locking up in Device Section on Windows - #22 by dartworth

Can confirm its crashing a lot especially when switching devices (between X1C’s and H2S mostly for us). Its near enough unusable at the moment.

any news on this one about Studio crashing? Mine crashes several times a day…no pattern recognizable…it crashes when scaling, when slicing, moving…whatever…then I recover, do exactly the same action, nothing happens….by now totaly unreliable software :-(…I have a powerful Windows 11 machine

i mad a bat file wich solves the problem by reduce the cores used in studio:

open a notepad put in :

cmd /c start “” /affinity FF “C:\Program Files\Bambu Studio\bambu-studio.exe”

rename the .txt file to .bat

voila

ps: if you placed the studio file in a other dir, change tje location in the command
