Installed GTA V through steam, and from that point it's been goofy. I went to open the game and it immediately started downloading all over again.

Once that download was done, I was able to run the game successfully. From there I found a YouTube video (<link deleted>) that's the video I followed step for step. Once all done, I went to test it out. Script Hook Critical Error, I see they updated GTA V and Script Hook isn't updated yet.

I downgrade the game following this YouTube guide (<link deleted>) and from there when I launch the game it goes to the black screen like its loading then within 10 seconds it crashes back to Rockstar launcher and says "Quiting" like I quit the game.

Any resolution for this issue?

Mod break: Don't link resources to original game files.

ScriptHookV has since been updated, so there is nothing to add to the discussion.
