Minecraft 1.13 Java crashes on launch

Java crashes at Minecraft 1.13 launch (game doesn't launch at all - always returns straight to launcher)

I'll include the Java crash report below.

Here's what I've done so far:

Uninstalled Java and tried 4 different versions, including the latest Oracle version (both JDK and JRE). Deleted and re-installed Minecraft.

All previous versions work, as well as all mods (launched from a different directory than vanilla 1.13). All mods and previous versions worked also when launching from the same directory (Application Support/minecraft).

Nothing seems to work for 1.13. The crash report is always the same, regardless of Java version:

#

1. A fatal error has been detected by the Java Runtime Environment:
   #

2. SIGSEGV (0xb) at pc=0x000000012685d8ce, pid=1238, tid=779
   #

3. JRE version: Java(TM) SE Runtime Environment (8.0_74-b02) (build 1.8.0_74-b02)

4. Java VM: Java HotSpot(TM) 64-Bit Server VM (25.74-b02 mixed mode bsd-amd64 compressed oops)

5. Problematic frame:

6. C [liblwjgl_opengl.dylib+0xd8ce]
   [error occurred during error reporting (printing problematic frame), id 0xe0000000]

1. Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

I would really, really appreciate any help. I've searched for days and haven't found a solution. Emailed Mojang support and they couldn't help. My boys are starting to get desperate.
