Issue with FLAIR interface is coming back on macos

Dear Flair users/experts,

I have installed flair on my macos sequoia 15.2 M4 and I had the following issue few months ago. The interface becomes strange, the geometry tab crashes. The first time I got this issue, @luillo provided a solution by suggesting to sudo port install tk +x11 (see https://fluka-forum.web.cern.ch/t/flair-on-macos-m4-issue-with-interface-and-geoviewer/6818)
Today, I have updated my ports and the issue is back again. I tried the exact same command and I also tried to force reinstall python and the dependencies.
The screenshot below shows the interface and when going in the geometry tab, I get the following error:
/usr/local/FLAIR/flair-3.4/flair: line 18: 9439 Bus error: 10 ${PYTHON} -O -W ignore ${DIR}/flair.py "$@"

Are you aware of how to solve this issue?
Thanks for your help.
Best regards,
Thomas
