At the end of last year, version of the game xxx (I don’t remember which) ran on java 17 without problems. Then I didn't run minecraft for a while and a couple of months ago I couldn't run version xxx. I haven't installed any new packages since then, so the problem is with one of the gentoo updates. Maybe from the log it will be possible to understand why the crash occurred?
log.txt

The log ends with "process exited with exit code 9" which is KILL, so your operating system is just killing MC. Most likely you just ran out of memory.

Can you check your system logs (journalctl, dmesg) after the game crashes to see if there's any information there?

I tried to set min/max 10240MB/20480MB. Did not help. lwjgl3ify has nothing to do with the sound system? I have a pure alsa without pulse/pipewire.

dmesg nothing was added after the crash. In the /var/log folder, the last modified file after the crash was 3 minutes ago (the moment the root session was opened to read the logs)

Prism Launcher -> use OpenAL (system) -> all ok.
