Maybe get a game config and the required mods. I would recommend F7YO's config (It can also be that the mod doesn't work anymore)

Not 100% sure but get a game config, or if you already got one download the most recent version(Since the new update many mods had to be updated) I recommend F7YO's config

That might work but if you deleted every file(Including the GTA Files) and then reinstalled. Will probably fix the problem, I expect the game to be done. Is it fixed?

Its probably that Script Hook V needs updating, every time Rockstar updates GTA V(The creator of SHV need to update it) You can downgrade but you won't have access to future GTA content.

@PanToPan Have you deleted all the GTA V files and the modded files then re-downloaded the game? If you haven't delete the files from the directory and empty the recycle bin, then Uninstall The game and reinstall. The modded files will be gone, the original GTA V files will be there.(Make a mods folder) A mods folder is for when you mess up, if you mess up in the future you simply delete the mods folder.

(In the directory) You got to make a scripts folder, right click and go to new(Click Folder) Rename it scripts(Put any future .asi .dll .ini in that folder for the mod to work)

The game only crashes when trying to get in a addon plane, if anyone has experienced this please help me with a solution

Last update I got tired of waiting for ScriptHook to update so I found tutorial that allows me to play GTA v in offline mode(I didn't notice I can't export my projects while offline mode. I tried the tutorials I seen online none worked) Please Help me and thank you
