EDIT since reporting, this looks to be a conflict with an add-ons use of OpenMP, not directly related to bevel ~ideasman42.

System Information
Operating system: MacOS 14.5
Graphics card: M3Max

Blender Version
Broken: 3.6.13, & 4.2
Worked: Neither

The second I hit CTRL + B and move the mouse to bevel an edge loop Blender immediately crashes before any visual representation of the bevel operation and goes straight to my desktop in both LTS versions of Blender.

Exact steps for others to reproduce the error

Add Cylinder

Select top or bottom edge loop

CTRL + B

move mouse

Crash straight to desktop

  • Also happens with mesh circle if I fill and extrude to be a cylinder shape (that's how it first started happening)

  • If I select all in edit mode and then bevel it works but that's not a fix

I can confirm that Blender also crashes to desktop in the same scenario on an Intel based machine.

System Information
Operating system: MacOS 14.5
Graphics card: AMD Radeon RX 6800 XT 16 GB

Blender Version
Broken: 4.2

Works as expected in Blender 4.1.1

Thanks, still unable to confirm. From logs, crash occurred during matrix calculation: adjust_the_cycle_or_chain() -> EIG_linear_solver_solve()
@Alaska hi, can you replicate this on mac?

I am personally unable to reproduce the issue in Blender 4.2.0.

Does the issue occur if you use default settings?

  1. Select from the top of Blender File -> Default -> Load Factory Settings
  2. Try and reproduce the issue.

Maybe there's some issue in macOS 14.5? I'm still on 14.4. I'll try updating and see how it goes.

Nope, updating to 14.5 didn't change the results for me.

@lichtwerk or @iss can you reproduce the issue on your Macs?

This is disappointing. It is weird that it's also happening in 3.6 LTS. Maybe it's limited to M3 or maybe I need to completely remove blender from my system and reinstall?

You can try that but i don't think it would make any difference.
In 3.6, does it work with OpenGL backend? 🤔

I just did a test and it's working fine in Blender 4.1. So I guess that's my fix for now.

I also tried multiple 3.6 versions including 3.6.0 and they all crash immediately.

Hi, relatively new to Blender, and having the same issue, was working fine until recently but now whenever I try to bevel an edge Blender immediately crashes.

Hello, I am experiencing the same issue. Strangely, the command works when I create a cube, for example, or even with Suzanne. However, as soon as I extrude something, Blender crashes immediately. I am attaching the crash log for reference.

On my Windows PC, I have the same add-ons and preferences, but no problems occur.

Oh, and when i use a bevel modifier it crashes too.

Thank you for sharing the information.

Considering we've now got 3 reports of the same issue, all with the same crash log, I believe we can confirm this issue. And since it is a crash, we should set it to high severity. Sadly it may not be fixed quickly as so far we haven't been able to confirm the issue.

I tried it on Blender 4.2.3 (the LTS) on MacOS 15.0.1, on a Macbook Pro with M3 silicon. It didn't crash.

The crash log shows it crashing in the Eigen routine that is called when trying to optimize the offsets when "loop slide" is on. But when I tested, loop slide was on, so I don't know what is going on.

Seeing people start to confirm this issue. I just want to update that’s it’s still happens in 4.2.3 with M3max.

The current fix is using blender 4.1.0.

It’s very strange. It doesn’t seem to be consistent under the same conditions.

I’m using an M2 Pro.

Looking at a similar crash dump in imagemagick, I wonder if the issue is similar to what is discussed there -- that MacOS has an open MP library dynamic library (libomp.dylib) and it has already initialized openMP when we try to do it again.
Erick-Phllips, perhaps you could try this:
when Blender is running, in a command window, type

ps x | grep Blender

There should be two lines of output. The first one (has Blender.app in it) starts is a process id, e.g., 34922. Next type

lsof -p 34922 | grep libomp.dynlib
(replace 34922 with your actual process id)
and report the results here.

I don't have a Mac to check, but this issue is likely caused by the molecular + add-on, all the crash reports listed in this issue contain a library core.cpython-311-darwin.so UUID=93c964b4-c344-38a6-bdbc-ff9f8d748b9a from an add-on in their image list. This UUID matches with the library in version 1.17.20 of the add-on. This library contains a statically linked copy of OpenMP which conflicts with Blender's version. Somebody already reported this issue to the add-on before: u3dreal/molecular-plus#43, but it doesn't seem like it got properly addressed there.

Thanks for tracking this down everyone. I will see if there's a way to check for this and use a workaround for bevel that avoids using the linear solver if this problem exists. But likely there are other areas of Blender that use openmp (e.g., I suspect motion matching), that will also fail under such circumstances,
