Error 12003 on launch and how can I contact Adobe support?

My illustrator app is crashing on the launch, showing error 12003 

"that it's likely on Adobe side and bla bla bla" 

how do I fix this issue and how can contact Adobe support? 
I tried to go through live chat and request to speak with agent, I get a response "our agents available at open hours" and that's it. No matter if I contact them during working hours or not.
