Thank you for the Link to homebrew issue! The solution is posted there: Reinstall octave from source.

brew reinstall --build-from-source octave

With the new installed octave I am able to use control toolbox.

You should really complaint to homebrew.
E.g. here:
https://github.com/Homebrew/homebrew-core/issues/201376#issuecomment-2663314707

It is their packaging issue. I compile both octave and control package from scratch and it works:

octave:4> G=tf(1)

Transfer function 'G' from input 'u1' to output ...

 y1:  1

Static gain.
octave:5> ver

The control package does not run properly.
I can install it, I can load it, but the simplest command fails. See below the error message after the command ">> G = tf(1)"

thx for support!

>> pkg load control
>> pkg list
