Immortals Fenyx Rising - Cinematic voices problem


I have install Ubisoft Connect then Immortals Fenyx Rising.

The game run perfectly fine, except in kinematics : all voices and subtitles are not synchronous with video.

In French audio, dialogs starts long after video (20-30 seconds). Voices are sometimes cut in the middle or entirely skipped. The same voice entry is also, sometimes, play multiples times.
Subtitles seems to follow voices : not displayed when voice skipped, etc.

With English voices, it seems better, but some of this bugs are still present and completely ruin the game experience.

I have tried multiples times with the first kinematic : the problems seems to be always the same, at the same moment.

Anyone with the same problem or a solution ?
