'Exception has been thrown by the target of an invocation' - Can't launch Studio

I was translating a simple project (a Word file) when suddenly I got an error and the Editor shut down. Clicking on the left pane on Project did nothing. 

I have restarted the computer but I can no longer launch Studio because I am getting this other error:

Error dialog box in Trados Studio with message 'Exception has been thrown by the target of an invocation.' and buttons for Knowledge Base and Community.

I have seen this error mentioned on the forum 4-5 years ago and the KB suggested is no longer available. How do I fix this? I need to complete my project.

Thank you!
