External Email - Use Caution
I setup the 7.3.2 release in an Ubuntu 20 VM by installing the .deb package available from under, https://secure-web.cisco.com/1Q2bcsIGqA45XXyvp1oUdk0FD9FaJp-NVNQeLjaHiqSpkZP...
The tutorial data I tested is from 2020 (not 2019), but that might not matter for that file (whose date is from 2018). I also use some soft links from $HOME to point to the freesurfer distribution and the tutorial data subdirectory, but again don't see that should make a difference. But freeview does open that individual file in my VM setup. if you want to try the same copy of the tutorial data I used you can get it from https://secure-web.cisco.com/1p3t4GUS5V08DKAzGkEoAeSvD3K-WIb6nplLAYdQGXnfAhc...
You can see the terminal session in the attached screenshot, freeview_ub20,jpg
If you did not use the .deb package for the install of 7.3.2, then I would try that. Otherwise there may be something going on with your shell environment.
There may be more info listed about the crash in /var/log/messages if you look there just after the crash. - R.
