Hello all, after upgrading from Leap 15.2 to 15.3 FreeCAD doesn't work anymore either, although it worked fine under 15.2. I have directly applied to the maintainer about this behaviour. I got no reaction. I have FreeCAD newly installed from the following repo: https://download.opensuse.org/repositories/science:/unstable/openSUSE_Leap_1... x86_64/FreeCAD-0.20~pre.1624371179.835e326652-lp153.265.2.x86_64.rpm The program starts without problems. However, when selecting the workbenches (workspaces in FC) the icons are grayed out. If I try to open any file the hourglass is spinning an nothing happens. The program execution seems to hang. In the .bash the following is displayed: $ FreeCAD FreeCAD 0.20, Libs: 0.20RUnknown © Juergen Riegel, Werner Mayer, Yorik van Havre and others 2001-2021 FreeCAD is free and open-source software licensed under the terms of LGPL2+ license.

Is there a debugger that I could run for a test to get clear which program section makes the segmentation fault? is doing? Can anyone help there? Package dependencies attached.
