Better to add your GTA V folder to Antivirus exceptions than turning it off.

LSPD:FR itself cuts performance a bit. Every callout or plugin you add, depending on how "heavy" it is, adds to performance loss.
Since you already have the game modded quite a bit, I'd say it's normal.
 
Try renaming the /LSPDFR folder in /Plugins to _LSPDFR. That disables any LSPD:FR plugins installed for now.
See if that helps or if your performance is still down.

You can try reinstalling the requirements, but it's very likely to be a Antivirus issue.
I know Avast has a bunch of issues with RagePluginHook.

Install the latest version of ScripthookVdotnet:

https://github.com/scripthookvdotnet/scripthookvdotnet-nightly/releases/tag/v3.6.0-nightly.114

1. Disable Ambient.Cop Spawns in your LSPDFR.ini:
AmbientSpawn.MaxCopsInArea = 0
AmbientSpawn.MaxSpawnedCopsInArea = 0

2. Change the plugin timeout threshold from 10000 to 60000 in the RagePluginHook.ini file; found in your Grand Theft Auto V folder.
Then locate to the GTAV/LSPDFR folder and open the LSPDFR.ini.
There change Main.PreloadAllModels to "false".

You have an invalid vehicle.
Rename mods to _mods. 

Disable game.blips in your LSPDFR.ini (GTAV/LSPDFR):
Main.DisableGameBlipHiding = true

Also, increase your PluginTimeoutThreshold to 60k. Open your RAGEPluginHook.ini and change the following setting:
PluginTimeoutThreshold=60000

Remove in /Plugins:
SirenSetting_Limit_Adjuster
CheckYourAmmo;

Remove in /Plugins/LSPDFR:
EmergencyCallouts;
HolsterSounds;
MegaPhoneUI;
OfficerPorciPlugin;
OP_Immersive_Dispatch
RegularCallouts;
UnitedCallouts;
 

You need to update RAGENativeUI.

Put the .xml and .dll into your GTAV folder. Download from here:
https://github.com/alexguirre/RAGENativeUI/releases

Clean out your GTAV-folder. Make sure no modded files exist- then reinstall LSPD:FR 0.49 manual.

Looks like you're using the wrong gameconfig. Please us this one (Yes, it works):
https://github.com/pnwparksfan/gameconfig

For the Packfile simply open the .ini in your GTAV-folder and change the value:
 

Change the plugin timeout threshold from 10000 to 60000 in the RagePluginHook.ini file; found in your Grand Theft Auto V folder.
Then locate to the GTAV/LSPDFR folder and open the LSPDFR.ini.
 
There change Main.PreloadAllModels to "false".
 
 

First things first; Computer+ and CalloutsV are highly outdated. Remove them.
Make sure you have Phone Notifications on and if you are on duty -> M -> Available for calls.
 
 
Since you have Callout manager, I recommend forcing one and seeing if it throws an error. 

Update / Install RAGENativeUI:
https://github.com/alexguirre/RAGENativeUI/releases
 
Simply extract the files to your GTAV main folder. 

That log is 6 days old.
If you crash when RagePluginHook "Validates System", please do the following for now, since it's a false positive:

Add your Grand Theft Auto V folder to Antivirus exceptions and your RagePluginHook.exe, too.
Then allow it on your device when the error pops up in the right corner.

For a quick and fast solution, please do this after doing the above:
1. Disable Windows Defender. 
2. Launch RagePluginHook.
3. Once it passes Validating System and Grand Theft Auto V starts, re-enable Windows Defender.

Not all of you will experience this, but for those who do, please follow the above. ^

There is no crash in your log so it might be related to outside influence; like a mods or scripts folder. 

You need to press Shift behind the vehicle first to "blip" them before activating your sirens.

You are missing NightYield.Callout.Infrastructure for NightYield's Callouts.
Move it from /Plugins/LSPDFR to your main GTA V folder. 
 

Sounds like your car packs are probably the cause.
 
Install one and then test after.
Keep that up until it crashes and then you'll know.

Callouts have set which peds spawn in said callouts.
 
You can change the models via OpenIV, and they'll be changed in the callout as well.
But which one appears is actually set / randomized. 

Please make sure to add your GTA V folder to your Antivirus exceptions.
 
Additionally, make sure your GTA V folder, GTA5.exe and RagePluginHook.exe (including the /LSPDFR folder) have all permissions for all users.

You edited them into the Patrol Unit; not the Motor Unit. 

Rename your mods folder to _mods.

If you have LML; disable it + vfs.dll, too.

We are working on the website.
 
For now; look what the error above says.
(Or simply don't go into the RPH settings and let RPH load up the game.)

Remove in /plugins/LSPDFR:
PeterUCallouts; CalloutsT; CalloutsV; Copper Callouts; CrazyCallouts; LSPDFR-Callout-Template; FayaCallouts; ForceACallout; FortZancudoCallouts; LencoBearCatControls; megaPhoneUI; OfficerprociPlugin; PriorityCallouts; RegularCallouts; redCallouts; RichAmbience; RichsPoliceEnhancements; Station 19 Callouts; terrcall; WildernessCallouts;  
And then reinstall the keys.ini from LSPD:FR 0.49 manual.
