Hi Sammy,
Please make a backup of your preferences here:
/Users/[username]/Library/Preferences/Ableton
Then delete it, and relaunch Live.
If you installed plugins recently, this can crash live, but not the extent that it should impossible to launch.
To test if plugins are causing this, please remove all content to 2 temporary folders from
/Library/Audio/Plug-Ins/Components
and
/Library/Audio/Plug-Ins/VST
Move it back if you still the same problem.
Still having issues?, please write
beta@ableton.com
Best,
Mads
