I have this issue as well. Also whenever I'm driving the patrol car at full speed, the game starts to freeze up, and it won't unfreeze for about 3 to 4 minutes.
When I'm playing GTAV without LSPDFR loaded, I don't get this issue.
Going to try to remove LSPDFR+, Arrest Manager, Traffic Policer, and Smart Radio. They are all made by Albo which could be the issue.
Furthermore, how do you fully remove those plugins? I tried to re-install LSPDFR and somehow those plugins are still loaded into the game.
