fs2020 black screen

Hello,

when the game, fs2020, arrives on the home page and it starts, the screen turns off, the PC continues to work but impossible to turn the screen back on, I have to stop everything and restart the PC, I don't haven't used fs 2020 for a month, before it worked perfectly.

Weird thing, I have the same problem on FS P3dv4, on the other hand FSX works perfectly.

if one of you has an explanation on the extinction of the screen?? thank you in advance
