My game language change by it self !?

When I buy the game it was in French , but Since the release of the guardian takedown the language of my game change automatically for English … how can I return it to French ? Am I the only one who this change happen ?

I think the patch notes for today said there has been a delay to languages other than German and English to do with the new DLC. It may be the main game has also been temporarily affected in the same way.

I hope it just the delay … thanks !!
