this might depend on how you install it I see you are using and /opt/ prefix. I just install it with `pybombs install gr-fhss_utils` and it works.
Maybe you are missing a dependency? FYI the FFT peak block you want is a simple hier block you could make without installing anything. Look at this file<https://github.com/sandialabs/gr-fhss_utils/blob/maint-3.8/python/fft_peak.py>.
