Black screen after selecting the game

Issue:
When I start pokemon ultra sun, I see the title of the game and then I can select to continue the game but then the screen turns black. I updated the graphics card and it worked during two days and then it happened this.

Can you go to Device Manager then open Properties for Intel HD Graphics 620 and click “Roll Back Driver” in the Driver tab? Windows most likely downgraded your driver automatically.
