Can't launch the game

I just wanted to play, I launched the game as I usualy do, a normal black screen and then … game closes and I’m back on the Blizzard app, game not running.
Everything was working perfectly yesterday and I haven’t touched anything.

So I checked on Internet :

  • I updated my graphics drivers
  • I used the repair tool
  • I deleted the Battle.net file (and at to relocalize the game folder)

Each of these solution did nothing …

I’ll be glad to have some help on this please !

This is usually caused by the Razer Synapse software. Are you using their peripherals?
