Game closes but remains open in background

Since 2 weeks I am unable to play the game, every time I open or launch the game, it works just fine, but then the window closes, and I can't re-open it, from the task manager I barely manage to terminate the activity that remains open in the back, still draining resources from my pc. I tried reinstalling, repairing, I did many things to try to resolve but I still cannot play the game
