Why is my Battlefield 5 game close immediately after I open it?

I had Battlefield 5 on my Xbox and unlocked almost everything. then I got a pc and downloaded it, it restarted me but I was fine with that. I play it a few times then moved on to some easier games to play on pc. then I need speed, which I had also previously played on my Xbox.  then after a few weeks of playing Need For Speed, I got some mods (the mod loader was called something like unite) which I did a lot of research on and I didn't think they would hurt any other games. the mods didn't work, and I uninstalled the mods. need for speed works fine but after I got those mods BF5 didn't work. Bf5 would try to open then immediately close not showing a loading screen nor even a black or white screen the pc uses before the game loads graphics. I tried everything I found on the internet, and nothing worked. Can anyone please help me?
