Problems with Duplicating objects

Hi there, I am struggling on my Mac Book Pro M1 with a problem with SketchUp:
one of the tools which I am constantly using in my workflow is the duplicate shortcut (Option Command).
Strangely I have to press the key combo for 4-5 times until it works once.
The same issue was on my old Macbook Pro, and somehow it is the only shortcut malfunctioning.

Does it work if you just tap Option once and release it?
