Hi, I installed the minecraft launcher via add/remove Software and it shows the launcher in the app thing but i cant start it. It just does nothing and i didnt find another way to install it. probably thats a dum question with an easy answer so i am sorry.
Did you install a compatible Java runtime?
What output do you get if you run the command in a terminal?

How did you install minecraft-launcher ? Why are you in a git repo with that name? 
Not really - there should be an executable file installed by the package. A .desktop file is a desktop application launcher (which describes various bits of information, e.g. the icon to be shown in menus and the executable file to be run).

I installed it from the arch wiki following this guide:
All the Arch wiki says is that
OK, but what did you do?
There are also two questions and a pointer that you have overlooked from above, please go back and review.

the first thing i tried was installing it with add/remove software but that didnt work so i tried the video
well in the viedo he said to do git clone AUR-link and then makepkg -si. I guess that solves why its agit repo.

OK, that makes sense, and the other good thing is you've found out how to install AUR packages "the Arch way" (using makepkg). 
Next, let's find out the name of the script installed that runs the launcher, and then try running it.
pacman -Ql minecraft-launcher
If that list is too long, look for files installed under /usr/bin (which is where most executables are placed:
pacman -Ql minecraft-launcher | grep usr/bin
That should provide you with an executable to run, e.g. /usr/bin/minecraft-launcher - run that in a terminal and check the output.

On testing the launcher, it seems to be working for me…
Just to rule it out, could you run it using bash?
bash -c /usr/bin/minecraft-launcher
Are you fully up-to-date?

This throws up some hits.
Can you try
LC_ALL=C /usr/bin/minecraft-launcher
?
If this works then it’s this issue:
and you need to fix your locale settings.

Thanks that was the problem! how can i fix the locale settings?
Make sure that the first two steps from https://wiki.archlinux.org/title/Installation_guide#Localization are in place.
(The wiki link gives the minimal steps needed, you'll need to use your brain to work out the locale setting you want 
)
These are my locale settings:
LANG=en_US.UTF-8
LC_ADDRESS=de_DE.UTF-8
LC_IDENTIFICATION=de_DE.UTF-8
LC_MEASUREMENT=de_DE.UTF-8
LC_MONETARY=de_DE.UTF-8
LC_NAME=de_DE.UTF-8
LC_NUMERIC=de_DE.UTF-8
LC_PAPER=de_DE.UTF-8
LC_TELEPHONE=de_DE.UTF-8
LC_TIME=de_DE.UTF-8
is it the problem that they dont match up? Like some german and some englisch?
Maybe - I haven't mixed locales, so you could try making them the same, but before doing that make sure that both
de_DE.UTF-8 UTF-8
...
en_US.UTF-8 UTF-8
are uncommented in /etc/locale.gen and then run sudo locale-gen . If that doesn't help then edit /etc/locale.conf and see if it helps. If none of those help then it's likely something in your DE, I seem to remember that KDE has its own way of setting the active locale...

Can I assume you also ran sudo locale-gen and it didn’t output any error?
Try logging out and in (or rebooting) to make sure the new locales are known to the session.
It might also be useful to have a read through Locale - ArchWiki in case I’m missing something…
yes it didnt.
I just rebooted but still the same error.
I will look into the wiki if i can find anything but atleast i can start minecraft with LC_ALL=C

Grand. As I say, it could be a KDE setting so make sure to check there too.
