Hi Zgajak,

I have checked today (1st September) on the new fresh installation of minecraft, and I don't see this error any more. I see that the new version of launcher has been released:  1st of Spetember.
Do still need Launcher_log file?

I see error   "GLIBC_2.29' not found"    on version:

[Info: 2022-08-29 20:48:06.288216338: Common.cpp(32)] Native Launcher Version: 1.1.28

(an entry taken from .minecraft/launcher_log.txt)

I have checked the .minecraft/launcher_log.txt like in the comment of @unknown, and I see "GLIBC_2.29' not found"

[Error: 2022-08-29 20:31:48.774274697: LauncherPluginLinux.cpp(20)] Failed to load /home/user/.minecraft/launcher/liblauncher.so: /lib64/libm.so.6: version `GLIBC_2.29' not found (required by /home/user/.minecraft/launcher/liblauncher.so)

I use:
NAME="openSUSE Leap"
VERSION="15.2"

I have the same issue on openSUSE:

If this is your first time running Minecraft, please ensure you are connected to the internet so we can download updates.

I have same problem from few days on openSUSE linux:

And it is not a problem with a lack of connection to the internet. And 'liblauncher.so' is on place.
