MCL-11993 recommends to switch to the new launcher (without any docs for how to do so). The fix of downloading the new version of the legacy-launcher fails (see MCL-12328)

So I downloaded https://launcher.mojang.com/download/Minecraft.tar.gz and unpacked it. It contains Minecraft/minecraft-launcher and inside "minecraft-launcher" which I started from a terminal. It exits right away without any error.

It does not look like its missing any libs:

ldd ./minecraft-launcher
linux-vdso.so.1 (0x00007fffa3937000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007f5d343e1000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f5d343bf000)
libstdc+.so.6 => /usr/lib64/libstdc+.so.6 (0x00007f5d341dd000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f5d341c3000)
libc.so.6 => /lib64/libc.so.6 (0x00007f5d33ffc000)
/lib64/ld-linux-x86-64.so.2 (0x00007f5d34408000)
libm.so.6 => /lib64/libm.so.6 (0x00007f5d33eb7000)

Attached an strace.log, but also there I don't see anything obvious.

 I can't report the verion that I got from the download, because there is no version indication in the files (not even running 'strings minecraft-launcher'). Maybe the dates help:
