I do not recommend mixing repositories like that. Sometimes this could work but 
usually this cause various problems. You could either build gnuradio from 
source, upgrade Debian to bookworm or work in a container/VM.

You have two gnuradio versions installed in parallel - 
/lib/libgnuradio-runtime.so.3.8.5 and 
/usr/local/lib/libgnuradio-runtime.so.3.10.3. The version in /lib is probably 
installed from package and the version in /usr/local/lib is probably installed 
from source, debian packages never put files in /usr/local/

Having two versions like this could cause various hard to debug problems so my 
advice is first to clean up your system, uninstall all gnuradio versions, 
manually check and remove all gnuradio's files in /usr and /usr/local (find 
/usr -name "*gnuradio*) and then install only one version.

You can use pybombs (I do not recommend this) to install multiple gnuradio 
versions in different prefixes but if you choose this method do not install 
gnuradio's packages from the apt repository and do not use /usr/ or /usr/local 
as prefix (install system wide).
