Re: issue (qt gui range) after uninstalling GR 3.9 and installing 3.8.2.0 [solved]
Got it !

After further investigation I came to the conclusion that my GRC (version 3.8.2.0) load 3.9 blocks. In my flowgraph, QT GUI frequency sink has a 'Normalized window power' parameter which has been introduced in GR 3.9.

Re: issue (qt gui range) after uninstalling GR 3.9 and installing 3.8.2.0
I found this closed issue on gnruradio github. with a solution which solved my issue. Meanwhile I don't understand why I got this erroneous /usr/share/gnuradio/grc/blocks/qtgui_range.block.yml file !
