"A Serious Error has occured" after latest patch download.

Hello,

I got this error pop whenever I try to boot up the game. It was running just fine last night. It suddenly occurred after the launcher downloaded some patch files. Adding - repair on shortcut doesn't help either. Can anyone please help me with this one ? Thank you very much, really looking forward to hear more about this matter. I'm currently working on my skyscale collection :(

This is the error code I get :
