If you have not already done so, see if you get a different result by double clicking on the Freeview.app icon under /Applications/freesurfer/7.2.0 with the mouse.
You can try this variation on what's been previously suggested.
1) run a bash shell
$ bash
2) setup freesurfer environment
$ export FREESURFER_HOME=/Applications/freesurfer/7.2.0
$ source $FREESURFER_HOME/SetUpFreeSurfer.sh
-------- freesurfer-darwin-macOS-7.2.0-20210713-aa8f76b --------
Setting up environment for FreeSurfer/FS-FAST (and FSL)
FREESURFER_HOME /Applications/freesurfer/7.2.0
FSFAST_HOME /Applications/freesurfer/7.2.0/fsfast
FSF_OUTPUT_FORMAT nii.gz
SUBJECTS_DIR /Applications/freesurfer/7.2.0/subjects
MNI_DIR /Applications/freesurfer/7.2.0/mni
3) Locate your license file (I name mine license.txt) in your home directory and check you can read its contents,
$ export FS_LICENSE=$HOME/license.txt
$ cat $FS_LICENSE
... check the output ...
... first line should contain email address ...
... followed by 3 more lines ...
4) set environment variable for debug
$ export QT_DEBUG_PLUGINS=1
5) run freeview with no arguments
$ which freeview
/Applications/freesurfer/7.2.0/bin/freeview
$ freeview
... an empty freeview window should appear and persist on the screen ...
At this point the last few lines of output in the terminal window should now be:
Got keys from plugin meta data ("svg", "svgz", "svg.gz")
QFactoryLoader::QFactoryLoader() checking directory path "/Applications/freesurfer/7.2.0/Freeview.app/Contents/MacOS/iconengines" ...
QFactoryLoader::QFactoryLoader() checking directory path "/Applications/freesurfer/7.2.0/Freeview.app/Contents/PlugIns/accessible" ...
QFactoryLoader::QFactoryLoader() checking directory path "/Applications/freesurfer/7.2.0/Freeview.app/Contents/MacOS/accessible" ...
6) Use the freeview application "File" pull down menu to select "load volume". In the window that comes up, click on the yellow folder icon to the r.h.s of the folder/file entry box under "Select Volume File". In the Finder window that comes up, navigate to /Applications/freesurfer/7.2.0/subjects/bert/mri and select the brain.mgz file.. Click on OPEN. That path/filename will appear in the load volume text entry box. Don't check/change any of the options for loading the volume and click OK.
The steps above worked for me to load that volume using an Intel MacPro laptop with the 7.2.0 release running under either MacOS 10.15.7 (Catlaina) or MacOS 11.4 (Big Sur) w/o freeview exiting or producing any further output in the terminal window. If it fails on your machine, you could send along the Qt debug output after the lines listed above. Please do not send the output from cat'ing your license file though.
