police radio doesn't work with ragepluginhook V24 it has to be V22 which is honestly more stable in my opinion. But did removing it fix the problem?
Also make sure you have all your mods up to date
is it just lspdfr or is it gta 5? because i had the same problem with police radio and gta 5 it would crash lspdfr because i was not on the correct version of ragehook at that time. It may be that you have a mod that is on a earlier or later version of ragehook than you. Check all your mods that you downloaded to make sure they are on the correct version of ragehook for that script. If not simply downgrade or upgrade your ragehook unless if you want to stay on that version on that plugin. If gta 5 is crashing than delete the plugin folder and test the script one after the other to see if one is crashing you game. If it is than delete it but make sure it isn't blocked by your computer before you delete the script if you really want to keep it.
