technical problem with the game, related to the game closing

about a few weeks ago a problem arose that is still relevant. The game <apex legends> when I close it in the evening or at night, does not close completely, that is, I find myself on the Windows desktop quickly as it should be, but in devmgmt.msc and in Steam it is listed as active for another 10-15 minutes, and takes up 4 GB of RAM. If at this time I turn off the PC or reboot, the PC simply freezes and I have to press the power button to turn off the PC. The game itself, the gameplay has no problems or complaints. When I play in the morning or during the day, I have never noticed this problem, but every time I play in the evening or at night (every day) there is the same problem. I have not found a single guide on the Internet how to solve it
