Madden 19 randomly exits fullscreen mode and enters windowed mode

Hello,

Title says most of it. The game will randomly enter windowed mode while im playing in fullscreen mode. My PC is usually only running origin and madden. System specs are ASUS motherboard, I5 processor, and NVIDIA GTX 1060. I'm unsure how to fix the problem. Any help would be greatly appreciated! 

Edit: My computer monitor is a samsung 27inch curved monitor, and happens to my friend on his 4k tv
