There are several common reasons behind this: RPH could require administrator privileges on your computer in order to hook. Antivirus is blocking RPH. You have another instance of RPH already hooked to your running game. Another DirectX hook (such as NVIDIA overlay program) was hooked to your running game thus preventing RPH to hook to your game.

Will this happen with RPH but without loading LSPDFR?

Did you update your gameconfig.xml? If no else do, remove ELS.

Remove your update.rpf and update2.rpf from the mods folder, and then re-install the mods exactly as described in the instructions for that vehicle.

That is not the issue. PluginTimeoutThreshold should be changed only if RPH indicates that it terminated LSPDFR because it caused the game to freeze. In this case, it's a CTD, and changing PluginTimeoutThreshold will not work. To @NNTK: Do you have a mods folder? If so, do you have any mods that would expand multiplayer character component slots? If so, remove that mod and try again. If not so, or if so but removing that mod did not work, try disable OpenIV.asi. (Rename it to OpenIV_ to do that).

Do you have mods folder, LML mods or anything similar?

Try to run RPH as an administrator.

Did you only have one RPH running?

LSPDFR has no relationship to SHV. SHV is a separate module that is used to operate a majority of community scripts that are not from the LSPDFR community (including ones made with Community SHV.NET, which is very capable of handling small scripts but not big plugins). LSPDFR, on the other hand, runs on RPH - another plugin loader and API for GTA V. It is derived from the original "Script Hook .NET" for GTA IV, and a lot of APIs look like SHDN ones. To resolve the SHV critical error, rename 'ScriptHookV.dll' to 'ScriptHookV_'. This workaround disables SHV and all other mods that depend on it.

Varies. It mainly depends on how Alexander Blade is doing and how Rockstar changes their game, but the longest time I've witnessed is about 2-3 weeks.

RAGENativeUI.Internals.Screen.get_ActualResolution() Update your RAGENativeUI at the GitHub repository releases page.

Just use Alt+Enter once you are in Story Mode.

I doubt if the log file even exists because 'Rage starts up, gets as far as "Validating Hook" and then it crashes to desktop'.

Complete the mission "Franklin and Lamar" so you can freeroam. LSPDFR will not work while a mission is active. You can skip cutscene.

Update your LSPDFR. Make sure you replace RPH with the one provided in the update package. This is because the RPH website seemingly stopped updating. Edit: Nevermind.

That is only helpful for RPH devs. Did your game start without RPH? If not, which I assume, rename your mods folder to _mods again. You can rename it back later. And if this works, provide a brief list of what you have in the mods folder.

If you replaced something but defaults are still there means that you could installing them in the wrong place. Use LML or a Modding DLC pack (like Albo's) one to make sure they are replaced correctly. Also did you keep your OpenIV.asi there?

Does the mic work well for other applications?

Modern plugin crash First, update ManiacCallouts to latest available version. If your issue persists, contact the author of that plugin. Evidence from log:

First, this has nothing to do with LSPDFR. This is something to do with your gun sound mods. If you go play Story Mode missions, you'll still find you have no gun sounds after all. Second, disabling mods folder means to rename a folder called "mods" to "_mods". This disables mods installed via OpenIV, but LSPDFR is loaded via RPH, uses a totally different folder called plugins.

If you Alt-Tab out of the game, can you see a Mic icon in the system tray, indicating GTA V is using the Mic?

Make sure you have the correct sample rate for your sirens. You should use tools like Audacity to match sample rate to the rate of the original file. Failing to do so will silence the whole AWC.

While that happening, can you perform a traffic stop?

What do you mean "microphone turns off"? Do you use PowerToys, or your microphone is already off; there could be a physical switch for your mic if it is a headset.
