Hey there!
1. Uninstall Callout Manager if installed.
2. Restart PC and reattempt
3. Reinstall LSPDFR
Go down the list only if you continue to crash after each step.
Hope this helps!
1. Send your Rage Plugin Hook Log.
2. The first test you can do is see if you can launch GTA by itself.
This mostly occurs when something is installed incorrectly in your GTA MODS folder.
