Game not closing after quit game

[Spitfire55]

Hello Farmers,

If I Quit Game from the main menu it closes and my pc returns to Windows.

if I join a server or play single player and then choose to quit game , the game doesn't close , this has been only recently been happening , all drivers are up to date?

Has anyone experienced this before and know if this is a bug within the game?

My other games aren't affected
