[Solved] Minecraft Crash C Locale Error

Hi,
I installed the minecraft-launcher package from yay and have the proprietary NVIDIA graphics driver installed. When I try to launch the launcher through shell, I get this output

ace@AceStrix ~]$ minecraft-launcher
terminate called after throwing an instance of 'std::runtime_error'
  what():  locale::facet::_S_create_c_locale name not valid
https://launchermeta.mojang.com/v1/products/launcher/6f083b80d5e6fabbc4236f81d0d8f8a350c665a9/linux.json

(process:35481): Gtk-WARNING **: 13:12:49.259: Locale not supported by C library.
        Using the fallback 'C' locale.
OK
terminate called after throwing an instance of 'std::runtime_error'
  what():  locale::facet::_S_create_c_locale name not valid

While setting up Arch Linux during installation I had used "en_GB.UTF-8" by editing /etc/locale.gen and then running the following

locale-gen
echo LANG=en_GB.UTF-8 > /etc/locale.conf
export LANG=en_GB.UTF-8

I am using the KDE environment with SDDM, an AMD CPU and dedicated NVIDIA GPU and I'm using the "jre-openjdk" package which can be confirmed with

 [ace@AceStrix ~]$ archlinux-java status
Available Java environments:
  java-23-openjdk (default)

Please let me know what the issue is and how to tackle this.

The command " LC_ALL=C minecraft-launcher " seems to work but without it I can't seem to launch it

Update:
I had only uncommented en_GB.UTF-8
but by also uncommenting en_US.UTF-8 and regenerating the locales, I can now use minecraft-launcher normally.
Marking it as solved but I still don't understand why this happens, please let me know.
