So I've updated to the newest version of GTA V because of the Cayo Perico Heist and I've managed to update RPH and Scripthook to be able to get into the game and roam around. My graphics mods appear to be working fine (just NVE and the addons for that) but my addon vehicles like Walter's RCMP DLS pack are NOT working and its showing all addon slots as disabled.
Anyone know how to fix this whilst avoiding a reinstall? Thanks in advance.
