Project file & Debug log uploads

To reproduce:
Go and get: https://github.com/BennetKrz/creality-print-nixos/blob/b45921872a5aab481948fa54c3f2db5d26354f64/native/default.nix

Build with: nix-build -E 'with import <nixpkgs> {}; callPackage ./default.nix {}'.

The build should complete successfully. Now try to start the application.
After starting for the first time there are opening some windows with errors:

The full log of the first start is this:

After that the second start behaves different. No window and just an error log:

After cleaning ~/.config/Creality i can reproduce the first start behavior. I think, that on the first start it starts with creating some kind of config, crashes and the config is corrupted. On consecutive starts, it fails because of the corrupted config.

Checklist of files to include

• Log file
• Project file

Anything else?

First off: Im sorry, if this is not the right place to ask questions about some kind of nixos specific questions. Just tell me and i will close the issue.

Could someone explain me, what am i missing in the build/environment to make this work?
Help in making this available for Nixos users would be appreciated.
