Version 1.19 cannot launch on Linux - LWJGL Natives are not on the classpath (caused by outdated launcher)

When I launch version 1.19 (modded or not) the client crashes about a second after I click Play.

This is because the natives are not on the classpath for some reason.

Log:

[10:42:11] [main/INFO]: Building optimized datafixer

Have you tried re-installing the launcher?
If that didn't work, Try the below steps.

1. Press WIN+R
2. In the window that appeared type in %appdata%
3. Then, navigate to .minecraft folder.
4. After that, delete that folder.
5. Then, Try launching minecraft.

That will most probably re-install LWJGL and its following classpaths.

I'll try those. I've mentioned I'm on Linux (not Windows) but I'll do the equivalent of that. You should've probably also mentioned that deleting .minecraft deletes all of your save games too, in case you give that advice to someone else.

This issue was resolved by updating Minecraft Launcher.

Oh, Alright. Thank you.

I had the same issue, I will try to update my launcher  too.
