This has happened to me too pretty much, to-desktop crashes with no error. It usually happens around 30 to 45 minutes into gameplay before you're sent to your desktop.
Something in the content is causing a lot of errors, a clean add-on folder won't work as I've tried this already.
This has happened to me twice now, first time was when I was arresting someone, and the second time was when I was killed in an unexpected raid as an officer, the moment I died and fell onto the floor my game crashed.
As far as I'm concerned it might be the new update causing stability issues.
Note that the game hasn't written an error report after crash, I've checked.
