une exception a été levée par la cible d'un appel. my problem is not solved

I have SDL 2019 and not using it on a regular basis (I prefer other products). But today, after closing SDL, appeared this : une exception a été levée par la cible d'un appel. I cannot solve the problem with the community comments 

Can someone help me because I cannot work and I need urgently to translate my document

thanks a lot
