No problem

Yep.
Your supposed to use this if you didn't already.

Glad you got it.

Figured it out! It was an extra option in the depths of my trainer: "Everyone Ignores Player".

I'm betting it's still in your trainer.  From what I've seen, only the trainer will freeze police AI.
 
However, have you added any new mods?

Hi officer107officer and every one who reads this.
I have found out where my problem is that LSPDFR does not work 100% I've seen when many Youtuber have installed LSPDFR and Ragepluginghook, so you have to run games through Ragepluginhook but before you can get into Ragepluginhook you should know some dll files. I have not got a box asking if I would allow windows to use the files that Ragepluginhook has in its folder if you know what I mean. I'll show you which box I'm talking about.
 
Does anyone know how to fix this or how I allow these files???

I'm not really seeing much in your log file which points to what is causing your crash and that is kinda odd. Try this, launch GTAV via Steam (not RPH) When the game fully loads, tab out of the game and launch RPH. Also, is your GTAV Folder added to your Anti Virus exceptions list? Just want to be sure its not being blocked and I kinda doubt it is because it sounds like this worked fine for you before. Usually when I get crashes I go back to what I installed last and remove it, but that doesn't seem to be the case if you said you just added cars and they worked.

Sorry for the delayed responses. RL happens. Go back to when your game didn't crash. Did you add anything new? Try this, go into your Main GTAV Folder and temporarily rename your mods folder to _mods , then launch RPH and see what happens.
Also, post an update RPH log with your next response along with any screenshots of errors you're receiving. 

Hi Officer107officer
Thank you very much for the "key" list. I will try to see if it works.

This can be found in the LSPDFR Frequently Asked Questions thread, along with a lot more information:
 
 

Try deleting Simple Trainer files and reinstall it. I've noticed there have been quite a few updates over the past few weeks. They are up to version 7.2 now

Didn't trainers require ScriptHookV, do you have that installed as well? I've seen Menyoo have issues together with LSPDFR so try Simple Trainer perhaps  You can find ScriptHookV here if that is what you're missing! http://www.dev-c.com/gtav/scripthookv/

Been a while, huh?
 
You know, when we first started making LSPDFR, the whole process was pretty much one big roller-coaster that didn't have any brakes:  there were the obvious highs when we'd finally add in something cool, but the low points were pretty hard as well - the amount of work that went into simply researching how things worked really took its toll as well.  And, of course, while this was all going on there just simply wasn't any stopping, we were a couple of (somewhat) real people who essentially lived in Los Santos for just about all of 2015, spending month after month pushing forward and trying to come up with things that everyone here would like to see.
 
So, of course, the grind and the pace of everything simply just wasn't sustainable and after 0.3, it's no secret that while the numbers and everything for our site are still on the up, month after month, things did slow down quite substantially for the actual mod itself.  But, we can tell you, this wasn't all bad news - it's afforded us the opportunity to take a step back and really look at the mod and figure out where we want to go next with it.  While our approach before was all about cramming as much new stuff as we could into a couple of months of development, we've now been able to look back at many of the original ideas and concepts that we had for LSPDFR and build on them.  Of course, with that being said, there's still a lot of new stuff crammed into 0.4!
 

 
With 0.4, we've taken the time to fix a couple of those "how the hell didn't they add this yet" moments :)
 
Aside from the cool little additions like this, though, the major theme of 0.4 is Character.  Ever since seeing the character system for GTA Online, it was always our goal to implement something similar in LSPDFR.  There's just something that much more personal and immersive about playing a game with your own character, and the possibilities that it offers are staggering too.  And yes, while mods like EUP are fantastic (and awesomely compatible with 0.4!), they still feel somewhat separate or distant.  With 0.4, this separation is gone.
 

 

 
No, these shots aren't taken from GTA Online.  This is our own, fully-featured, LSPDFR Character Creator.
 
Of course, we'll talk more about the new Character features in LSPDFR 0.4 later.  The Character Creator menu shown above is obviously only one part of what's new in this regard, although hopefully it emphasizes the effort that we've gone to.  Thanks to some of the new additions like this, much of 0.4 actually looks and feels like an entirely new mod altogether.
 

 
Officer Ronson and his clones obviously couldn't make it to the flashlight party. 
 
Stay tuned!  We'll be sharing more about 0.4 soon.

They are most likely the cause, or usually are in your case.
