Blender Version
Broken: version: 3.3.0 Alpha, branch: master, commit date: 2022-05-25 21:21, hash: dc6fe73e70
Worked: (newest version of Blender that worked as expected)

Short description of error
Add the new Hair curve random to an object, and add Mesh to Volume or Volume Displace and press apply on any of the modifiers, and blender will crash

Exact steps for others to reproduce the error

add the curve Hair random to an object
add Mesh to Volume or Volume Displace from the modifier tab
click apply or Ctrl + A on the modifier tab and blender will crash

I know this is an experimental tool, But I hope this can be fixed.

Thanks for the report.

I'm pretty sure this is caused by 78fc5ea1c3 assuming that object->data is a mesh.

The fix is simple.
