So I found out that my LSPDFR would crash on startup if I had made any changes to the vehicle.meta folder for my game. However, this is a problem because now I cant fix the handling lines for my cars and now I'm taking corners on two wheels and flipping the car during pursuits. So how can I fix the handling lines without crashing the game?

Just started having this issue as well, it never happened before this previous title update to the game. I'm suspecting its something to do with Rockstar and their "hacking measures".

I've seemed to figure it out, at least on my end. Through some trial and error, I found that changing specifically the park ranger (pranger) handling ID was responsible. I was able to modify every other cars handling ID, LOD distance, tint value, everything.. with no issue. So maybe this is your issue as well.

I tried what you said and left the pranger handlingID as the default. I swapped the ID's for the POLICE, POLICE2, POLICE3, SHERIFF, SHERIFF2, and both FBI slots. the game crashed on start up but replacing the .meta file with the one from the vanilla game will allow the game to start and work again

That's what I initially had to do as well. What you may want to do is go through all those slots (police,police2, etc.), and change them one by one and start your game up for each one. It's a bit tedious for like.. a half hour or so, but it'll really let you narrow down your problem and figure out which one to leave alone.
