You can remove what you installed there one-by-one and test after each removal. If that doesnt work, you may have to remove and completely re-install LML.

Remove ScriptHookV.dll and try again.

Here.

If renaming mods to _mods works, then the issue is a mods folder problem. 

If renaming mods to _mods works, rename _mods back to mods and try:
Installing the gameconfig by PNWParks as well as the Heap and Packfile Adjusters.
If that still doesnt work, you can remove what you added recently one by one and test after each removal.
If that still doesnt work, you will have to restart the mods folder.

No because I want you to re-install the full manual version of LSPDFR.

Rename mods to _mods and try again.

Then slowly add back your plugins and test after each adding.

The point is that if you install a bunch of stuff and then test after everything, it will most likely crash. If the first 4 steps simply do not work, there are too many variables to test and restarting fresh may be your best option. That way we can ascertain whether or not RPH will work with your base game with no mods at all.

Go into the lspdfr.ini in the lspdfr folder in the Main Directory and make the following look like below:
Ambient.DisableEscapedSuspectEncounter = true

Additionally, change your Plugin Timeout Threshold to be higher:

Accessing RagePluginHook Settings

Changing Your Plugin Timeout Threshold
 

Yeah I can see the line relating to ELS. What I want you to do is remove whatever xml's you have in ELS/pack_default. Then add them one-at-a-time and test after each addition. See if there are any problems.

You can try editing the visualsettings.dat (found in mods > update > update.rpf > common > data). Please change the following entries:

car.defaultlight.day.emissive.on 1700.00
car.defaultlight.night.emissive.on 1100.00

Lastly, make sure your PostFX and Shader Quality are set to at least High.

You need to ensure that CalloutInterfaceAPI is installed to the Main Directory and not into Plugins/LSPDFR.

If you simply don't have it, re-install SuperCallouts as it is included in that download.

If you used Ultimate Backup, re-download UB. Then move the UB folder in Plugins/LSPDFR of the download into Plugins/LSPDFR in your Main Directory.

If you used base LSPDFR, re-download manual LSPDFR. Then go into the download and then lspdfr/data and copy the agency.xml to lspdfr/data in the Main Directory.

Go into the CommandLine.txt in the Main Directory and remove everything in there and add "-windowed" without the parenthesis. 

Additionally, re-download the manual LSPDFR. Go into lspdfr/data path in the download and copy over the inventory.xml from there to lspdfr/data path in the Main Directory. Then try again.

Google Resource Adjuster and install it to the Main Directory.

It's a false positive. You can add the Main Directory as an exception to the anti-virus and re-install manual LSPDFR and restart PC. That should help.

Remove Code Red Callouts. Try again. If it still crashes, rename mods to _mods and retry.

You can try using the update SHV.NET from here. If that still doesn't work, you sadly won't be able to use anything that utilizes SHV.NET. As it sometimes flat out won't work on a per user basis.

Arrests are only tracked is done via LSPDFR. They will not count if done via StopThePed.

It can if you aren't using a modified gameconfig and Heap and Packfile Adjusters. I recommend the gameconfig by PNWParks.

Rename Scripts to _Scripts and remove all the ScriptHookV.NET files. Then try using RPH/LSPDFR again.

Rename mods to _mods and see if the issue persists.

Go into the lspdfr.ini and add or change the following to reflect the line below:
Ambient.DisableEscapedSuspectEncounter = true

If the issue is still occurring, rename mods to _mods and see if the issue persists.

Re-install GrammarPolice. You have either missing or incorrectly installed files.

Is there an issue with downloading it?
