Blender crashes with exception_access_violation

Hi everyone,

Im new to blender and im following this beginner tutorial: https://www.youtube.com/watch?v=bLw0HwphXO
The goal of this tutorial is to create a donut with sprinkles.

However in part 10 of the series, when I add a subdivision surface modifier to the sprinkle and go to edit mode, blender crashes with an exception_access_violation.

Unfortunately new users can not upload attachments on this forum.
You can find the .blend file and the crash report on this github repo: https://github.com/clanggoo/BlenderIssues

Im not sure if this is a bug or if I messed up somehow, any advise would be greatly appreciated.

Steps to reproduce:

  • Download donut.blend from github
  • From the Scene Collection select the Sprinkle
  • Add a subdivision surface modifier
  • Enter edit mode

Hmmm, I downloaded your file and got a similar crash on Linux (crashes like this are very rare for me).
Looking at your file I thought the first culprit maybe the geometry nodes as they mess with geometry.
I checked the “as instance” checkbox in the sprinkle object info node …and no more crashes! :smiley:

I can not give a technical explanation of why, maybe someone else can enlighten us!

Fantastic it works for me as well, thank you very much! :grinning:

In the tutorial he also checks it, I just missed it somehow.
As of the geometry nodes, this part is a bit confusing to me I certainly need to rewatch it.

Do not worry, they are a bit hard to grasp, you just need to go little by little. They are well worth looking into at some point as they open a world of possibilities and will get better and more useful as time goes by.

I do not think they should crash blender like that, GN nodes were my first thought because they are under heavy development.
