Closed

System Information
Operating system: Windows 11
Graphics card: RTX3060 12GB

Blender Version
Broken: 4.1

When model is subdivided 5 times using multires modifier, selecting "Randomize" from the sculpt menu crashes the system to the desktop with no error message.

Exact steps for others to reproduce the error

Open the blend attached. Select the female model (should be the only one).
Verify that it has the multires modifier attached, and that it has 5 levels.
Go into sculpt mode on the model.
Choose "Randomize" from the sculpt menu.
Click on the model and drag. Instead of adding random noise, it will crash to the desktop.

Similar to #120187

Except, I am able to sculpt for a bit. Randomize crashes it right off.

Sculpting with multires modifier tested working on 3.6 and 4.0.
Only 4.1 causes crash.
Attached is System_info text from crashing version.

Memory statistics say Blender is taking 1876.567 MB (Peak memory).
Windows is saying that 23.1GB of memory is being used (total), and that 105GB of RAM is available.
