      I tried running the shenandoah GC to compare performance. Now I know this GC is experimental but its failure is not the bug, the lack of a crash report is.

      Do do this, I need to run in a java 12 environment, so I changed my java runtime from 'bundled' to

      /usr/lib/jvm/java-12-openjdk/bin/java
      

      And Minecraft starts and runs just fine.
      As a next step, I changed the arguments from the default

      -Xmx2G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M
      

      To the custom

      -Xmx2G -XX:+UnlockExperimentalVMOptions -XX:+UseShenandoahGC
      

      Basically I removed all custom GC arguments and replaced them with the use shenandoah argument.

      Now minecraft crashes after loading, but it doesn't leave a crash log for some reason.
