Not sure where the conflict is but anytime I do a car stop and end up wanting to arrest the subject it becomes impossible. I'll order the subject out of the car and then I'll have no option to arrest or detain or anything. No prompts at all. Can't even hold down the button either. 

 

I only have albo lspdfr+, arrest manager, smart radio, and traffic policer for additional modifications. I also use a controller to play primarily. 

 

Any help would be much appreciated. 

I'm having the same issue. Any chance you figured out the fix?

I am not sure because I don´t use the vanilla functions. But I guess you only can arrest drivers with gunpoint. Try Stop the ped. With it you can interact more to peds and always arrest them 🙂
