Unable to launch - Illustrator on macOS

I downloaded the latest version of illustrator to my macbook pro 2017 a couple of weeks ago and immediatley illustrator wouldnt launch. it would just hang on the open page 'initializing'. i then uninstalled and tried to install a previous older version of illustrator which also then wouldnt work. i tried various versions and none would launch. so i then uninstalled the lot, tried a clean up as some forums had mentioned this might work and then tried re downloading Illustrator (an older version again) to now luck.

I have trief various versions, restarted multiple times and no matter what i do i cant get illustrator working 😞
