System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 1060 6GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 461.09

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-08-29 02:11, hash: blender/blender@2f7258d618
Worked: (newest version of Blender that worked as expected)

Short description of error
When you select a libary in the Materials Libary VX, but no library item, and click at the Apply to Selected button, then you get an error.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

Activate the material library VX addon
Navigate to Material Properties and to the Material Library VX
Choose one of the libraries. But don't choose any content of it
Click at the Apply to Selected button or the Preview Material button

The error itself is logical. There is no library item selected. And so there is also nothing to apply. But the better way would be to catch this error message and display a warning instead.

Hi, thanks for the report. I can confirm with 3.0.0: 42546db49089

But same issue already exists on tracker: #84444 (Material Library VX: Exception when attempting to apply a material without one existing)

Will merge this into #84444 :)
