Crash on Loading and Populating World

Hello, I am modding GTA 5 with LSPDFR, a bunch of plugins that enhance the callouts for it and EUP. I have had success in adding police vehicles into the latest patch day and into patch day 22, and have used them in game, but it seems that after I place a certain amount of said police cars into the patch day file, my game will crash on the loading screen at "Loading and Populating World". I have narrowed it down to the adding of vehicles after much trial and error of using a clean mods folder and clean install of GTA 5. I was able to get it to load with LSPDFR and all my other plugins and then when I try add 1-3 more standalone vehicles, it crashes. Also, I used a vehicle pack with a vehicle meta file and it worked, but I wanted my own skin and model so I replaced the singular .ytd's and .ytf's, it crashed. The last sentence I think is important because the second I try to add my own model and texture, it crashes .I have tried using 3 different game configs, using pack file adjusters and heap limit adjusters and yet I cannot seem to add more than 3-5 modded vehicles that are named "POLICE" or "POLICE2", for example. Advice or suggestions will be greatly appreciated.
