Using Forge 2309, CC 0.0.600.0 and Extra Utilities 1.4.2. Everything loads and apparently generates as normal, but from the ESC menu when I click on Options or Mod Options it crashes.

EDIT: I ran it again and it wasn't waiting for me to click on options, but rather just happens seconds after the map loads.

EDIT 2: Just tried it with Extra utilities 1.4.3 and still crashes after a few seconds.

It's already fixed in the latest build.
