Based on previous findings, I uninstalled everything java, uninstalled the launcher, renamed .minecraft folder, and started a brand new installation.

Started a new 1.19-pre2 world, and the launcher downloaded the 17.0.3 runtime, and put it in the folder ".minecraft/runtime/java-runtime-gamma", and started the game.

It works for me now.

Edit:System is Manjaro Linux, gnome.

I made a new install of the launcher on a (almost) fresh installation of Manjaro, on a laptop. That install works with 1.19-pre2...

openjdk 17.0.3

Interesting enough,  first start of 1.19-pre2 created a "java-runtime-gamma" folder. See my question about that in a previous post.

Just tried to launch a 1.19pre-2 minecraft server on my linux system, and it worked. No errors at all.

java in use is:
openjdk version "18.0.1.1" 2022-04-22
OpenJDK Runtime Environment (build 18.0.1.1+2)
OpenJDK 64-Bit Server VM (build 18.0.1.1+2, mixed mode)

I also noticed that the bundled java is (in ~/.minecraft/runtime/) :
jre-legacy is marked as version 8u202
java-runtime-alpha is marked as version 16.0.1.9.1 and for
java-runtime-beta it is marked as version 17.0.1.12.1

I have no java-runtime-gamma folder...
this link suggest that maybe it should be such a folder present?
https://launchermeta.mojang.com/v1/products/java-runtime/2ec0cc96c44e5a76b9c8b7c39df7210883d12871/all.json

and the java version should be 17.0.3 in such a case.

System: Manjaro Linux (Gnome).
$ archlinux-java status  
Available Java environments:
  java-11-openjdk
  java-17-temurin
  java-18-openjdk (default)
  java-8-openjdk
I can run snapshot 22w16a and 22w17a with default launcher, on as low as openjdk 8.

Launcher is: Linux 5.10.109-1-MANJARO 2.3.173 torsdag 28 april 2022 21:57:25

Switching to a higher java version does not help, can't start anything above 22w17a.
Tried to set and use a jre directly "/usr/lib/jvm/java-18-openjdk/bin/jar" wont work.

Once, and only once, I got this log message in the launcher:
18:32:40.816
Preparing to launch minecraft client for 1.19-pre2
18:32:41.724
Minecraft client 1.19-pre2 is ready to start.

18:32:42.086
Process crashed with exit code 1

On almost every other attempt, I am only getting a "waiting for log output"

To add to it. Seems like it only affects barrels that was in the world already (in my case from earlier snapshots).

Edit: Forgot to mention that I am playing on snapsgot 19w11a

If I travel to a villlage, that I have visited earlier, and place down a barrel next to a "village generated" one, there are no problem at all opening the new barrel.
But, as soon as I try to open the "village generated", I got an crash with ticking entity. 

Description: Ticking block entity
java.lang.IllegalStateException: POI never registered at eu{x=286, y=74, z=1565}

If I do F3+I on both, I am getting the exact same result.

/setblock 288 74 1564 minecraft:barrel[facing=up,open=false]{Items:[]}
/setblock 286 74 1565 minecraft:barrel[facing=up,open=false]{Items:[]}
