PROBLEM VIA STEAM

Since this morning, December 25, the game, via Steam, seems to no longer start correctly.
When I try to open the game it opens in a window (completely black) after a second it closes distorting the Path Of Exile 2 startup sound, then every time I try to reopen the window it closes again as an icon.
This startup problem did not happen until yesterday and now I have almost 60 hours of gameplay.
