I am having the same problem. If I accept any callouts my game crashes. If I go to interact with a driver after pulling them over, my game crashes. I have found that if I point a gun and press E the menu will open and I can continue, its weird. Even if I do that- when I try to put an arrested civilian in my car, it crashes as well. I thought I didn't have enough RAM so I bought 8gb more and I'm obviously stupid for that because it still doesn't work. I have no extra plugins and I have not touched anything in the folders, just a simple GTA install then LSPDFR install. Currently unplayable until I can get help. Tried re-installing everything 3 times.
