2.6.0-alpha6 segvault on startup

[angaz]

Description of the bug

Hi, I'm trying to build 2.6.0-alpha6 on Nix. I have the following changes:

    (prusa-slicer.overrideAttrs (oldAttrs:
    let
      nanosvg = stdenv.mkDerivation rec {
        pname = "nanosvg";
        version = "2022.12.04";

        nativeBuildInputs = [ cmake ];

        src = fetchFromGitHub {
          owner = "fltk";
          repo = "nanosvg";
          rev = "abcd277ea45e9098bed752cf9c6875b533c0892f";
          sha256 = "sha256-WNdAYu66ggpSYJ8Kt57yEA4mSTv+Rvzj9Rm1q765HpY=";
        };
      };
      wxGTK-prusa = wxGTK32.overrideAttrs (old: rec {
        pname = "wxwidgets-prusa3d-patched";
        version = "3.2.0-patched";

        nativeBuildInputs = [ cmake ] ++ old.nativeBuildInputs;

        src = fetchFromGitHub {
          owner = "prusa3d";
          repo = "wxWidgets";
          rev = "0b49beaacce17d90f0c370ecd73221abd089667a";
          hash = "sha256-kipN6WqJs/RlRYxw52s8xiYaU1bsGRcqBvHTRn+blxQ=";
          fetchSubmodules = true;
        };
      });
    in
    rec {
      version = "2.6.0-alpha6";

      patches = null;

      buildInputs = [
        nanosvg
        qhull
        tbb_2021_8
        wxGTK-prusa
      ] ++ lib.lists.remove tbb oldAttrs.buildInputs;

      preConfigure = ''
        sed -i '448d' CMakeLists.txt
      '';

      src = fetchFromGitHub {
        owner = "prusa3d";
        repo = "PrusaSlicer";
        sha256 = "sha256-mz2N4xwPvmCWV+iCdGEVhmYsRcsshqdI8rA6+levVaw=";
        rev = "version_${version}";
      };
    }))

The compilation is successful, but when I try to start prusa-slicer, it asks if I want to use my 2.5.x settings, it doesn't matter what I choose, then there is the segfault.

Running in GDB, I get the following backtrace:

I don't know where to continue from here. So any help would be appreciated. I will try to compile alpha5 and see if it works.
