Hello,
I believe I found out what was causing the System.AccessViolationException issue on my GTA V after the Bikers update. Turns out I had a counter-measure against online vehicles being removed in singleplayer. All I did was unstick it and well, it worked perfectly. I also spawned the Zentorno and the Kuruma2 to test out (it was crashing before if spawning them).
For the LSPDFR players out there, clear all your plugins and mods installed, make a full legit copy of your GTA V folder and start from the beggining, feel free to try online RAGE Plugin Hook first, but once you have installed the LSPDFR, make sure you extract the RageHook 0.47 overwriting the previous RAGE Plugin Hook files (which comes with LSPDFR).
I hope this helps anyone out there.
Thank you RageHook for providing us this awesome tool, thank you LSPDFR staff for all the hard work put into it and happy gaming to all of you!
