Your crash report listed an Intel Mac running BigSur 11.4. The screenshot below shows running the freesurfer 7.2.0 release installed on an Intel Mac running BigSur 11.4 (after installing the pkg file from https://secure-web.cisco.com/1w0xxEMjJUzMzaNI7qL3KE_kI0NAwbdBtOtoYDxzwRigNsm...). In the terminal window you will see FS_LICENSE was manually set in the environment to point to the license.txt file. But the environment variable QT_MAC_WANTS_LAYER is not in the environment at all. After opening an empty freeview window, the volume /Applications/freesurfer/7.2.0/subjects/bert/mri/brain.mgz was loaded. Please give that a try on your machine. - R.
