SDL is not opening since the last update. Error message "Une erreur inattendue s'est produite lors du chargement des services de plug-ins globaux".

Hello,

I have a file to deliver at 2 pm and made the mistake of letting SDL install the latest plug-ins and restart.
I get an error message from SDL when I try to start the programme (SDL Studio 2017) ever since.

What can I do ?

Thanks


Caroline
