Problem with "Align: Picked Points"

[Anna486]

OS: LinuxMint 20.3
Blender Version: 3.2.2
Problem: Option Align Picked Points doesn't work. I select Base Object, Align Object, hit "Align" and get such an error message. I used this method ( first points, later weight paint) on blender 2.79b and blender 2.83.6 (with proper version of addon) and always worked like a charm. So what's wrong?
