The gnuradio's version in Fedora 31 is 3.7.13.5-6.fc31.x86_64 and 5.4.17-200 is
the version of the Linux kernel.
You can find the newer version 3.8 in the COPR repository

The Fedora official package does not provide these QT GUI blocks, actually it
does not provide any QT blocks. The most probable reason is that Qt4 was
removed from Fedora 31 and gnruadio 3.7 still uses Qt4. How did you installed
these blocks?

Can you take a backtrace? First install the needed tools and debuginfo packages
sudo dnf install dnf-utils gdb
sudo debuginfo-install python3 gnuradio
then run
gdb -ex run -ex bt --args /usr/bin/python2 /usr/bin/gnuradio-companion
do whatever is needed to reproduce the segmentation fault and then provide the
gdb output from your terminal.

Vasil
