Don't mind Hold My Gun plugin, it freezes and gets terminated when it couldn't check for updates. I have installed Jurisdiction+ but I couldn't get BCSO working before that, either. So Jurisdiction+ shouldn't be the cause. In the log, I went on duty, started a callout to try if I could accept it and tried to pull over a vehicle. Then I quit the game.
After the callout which I couldn't accept, the map remained expanded with the red&blue circle flashing on it.
