What did you do to get this issue?
Issue is most probably caused due to addon I’m trying to add to singleplayer. I overcome rage::fiPackfile encryption error uppon inicialization by encrypting dlc.rpf file using affix (ArchiveFix) which allowed me to start and load game to main menu. rage::fiPackfile encryption error occures one again after selecting “Story Mode” and loading files. I tried unpack dlc.rpf, encrypt vehicles.rpf, pack it again and encrypt dlc.rpf. No difference.
What server did you get this issue on?
Singleplayer, Launching Story Mode

If an issue with starting:
GTA V folder screenshot
GTA V/update/x64/dlcpacks screenshot
Nothing changed inside, all changes were made in FiveM folder.
Added /dlclist.xml to /citizen/common-sp/data/
Added /cars/ngtr35nismo17/ to /citizen/dlc/ (properly mapped in dlclist.xml)
Filepath to FiveM folder
C:\Users\user\AppData\Local\FiveM
FiveM client folder screenshot
Did you try to disable/uninstall your Anti-virus?
Not related.

I’m fully aware of lack of documentation for FiveM SP, I managed to dig up some info from posts and forums to work around. This seems like an memory error or difficulty with resource mapping/accessing cause by encryption. You might have better idea. I can get rid of what I added to revert changes and start it normally, but my intention is to make it work if it’s possible. Appreciate any help
