I bought the game Sonic Forces on Steam and it was working fine at first. Then I decided to alt-tab and the game became windowed mode and black. ( you can still hear the sound and press buttons, just no visuals). I tried to restart pc, verify files of the game, and even uninstalled and installed it again but I can't even play the game anymore because it always starts like that now.
I didn't find the right solution from the Internet.
