To keep things simple and straightforward, the RPH is acting strange all of a sudden. The last time it was working for LSPDFR was this past Thursday, and today is actually the first time I decided to launch it since that previous date in particular. I have no idea if the recent RPH issues are related, but on Thursday, a plugin I installed called Stop the Ped crashed the LSPD First Response.dll plugin in-game after trying to send away an arrested suspect who was in custody in a private transport vehicle. The game itself did not crash, but the LSPD First Response.dll plugin itself crashed, though. Fast forward to today, RPH crashed on the loading screen when trying to go into story mode with the RPH plugin. The second time, it did successfully load into story mode on my game save, but crashed the entire game when trying to load the EUP Plugin which is also installed in my GTA 5 directory with EUP - Law and Order. I am currently wondering if anybody knows why these problems keep persisting. Down below I believe is the RPH Crash Log.

(SOLVED) - I managed to figure out what my issues were. I was missing some dependent file types that were required to run what I had set up.
