Operating system: Windows-10-10.0.19043-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 496.76

Blender Version
Broken: version: 3.0.0, branch: master, commit date: 2021-12-02 18:35, hash: blender/blender@f1cca30557
Worked: (newest version of Blender that worked as expected)

Addon Information
Name: Material Utilities (2, 2, 0)
Author: MichaleW, ChrisHinde

Short Description
I clean some objects to eliminate materials that are not present. Blender randomly assigns materials to parts of the mesh

I select an object to clean, in which there are unassigned materials. Run "clean material slot" but then it makes the mistake I am talking about.
In version 2.93 it works perfectly

Steps to Reproduce

  • Open default file
  • Enable Material Utilities addon
  • Add 2-3 slots material slots (do not assign them to any part of the mesh)
  • {nav Shift Q > Clean Slots > Clean Material slots}
