Thii crash affect only my last build I have done after upgrading my platform to ubuntu 24.04.
The snap version:

OS: Ubuntu Core 22 (GNOME/gnome-wayland)
Word size of FreeCAD: 64-bit
Version: 2024.409.0.38991 (Git) Snap 132
Build type: Release
Branch: tag: 20240407stable
Hash: 973e4821bcd19a5a1af9ae3e1d2ed961aad0a8ab
Python 3.10.12, Qt 5.15.10, Coin 4.0.1rt, Vtk 7.1.1, OCC 7.7.2
Locale: English/United States (en_US)

works well also in a wayland session of ubuntu 24.04.

If I remeber well also my previous build done in ubuntu 22.04 worked in a wayland session. I can't understand what changed in the last build.

I have just seen that this problem was already dealt at void-linux/void-packages#41425.
The solution of executing "QT_QPA_PLATFORM=xcb FreeCAD" instead of simple "FreeCAD" worked also for me.
But would it possible to insert this option inside the FreeCAD code instead of having to put it in the command line ?.
