Fedora/KDE: Application only works when launched from terminal due to missing shell environment variables

[Eispala]

Hello,
i am using Nobara (Fedora) with KDE Plasma.
The program was compiled from source.

It only works if i launch it from the terminal.
To make it work from the Application Menu i changed the Exec line from this:

Exec=/usr/local/bin/oversteer

To this:
Exec=bash -c 'source ~/.bashrc && /usr/local/bin/oversteer

For me the complete working ApplicationMenu-File looks like this:

[Desktop Entry]
Categories=Game;Utility;
Comment=Steering Wheel Manager
Exec=bash -c 'source ~/.bashrc && /usr/local/bin/oversteer'
Icon=io.github.berarma.Oversteer
Keywords=game;racing;cars;wheels
Name=Oversteer
NoDisplay=false
Path=
PrefersNonDefaultGPU=false
StartupNotify=false
StartupWMClass=oversteer
Terminal=false
TerminalOptions=
Type=Application
X-KDE-SubstituteUID=false
X-KDE-Username=

That shouldn't be needed and it isn't an issue for anyone else.

What's the error in the terminal with this command?

bash -c '/usr/local/bin/oversteer'

I'm providing Fedora package in copr: https://copr.fedorainfracloud.org/coprs/peem/oversteer, never had issues like that with oversteer.
