I tried to update my game through steam. It’s always automatic and it doesn’t seem that i have to update anything. But it still pops up with the error. 
It’s really annoying. And i can’t fix it. I followed every step. i backed up all files (Normal gta with no mods) and put fivereborn in there. My game is not pirated and it’s updated everytime there is a update. If someone could help that would be fantastic. (I am using windows 10 if that helps)
Random question that probably won’t solve anything, but where did you put FiveReborn?
If this many DLCs seem to be missing, have you tried verifying your game? It seems you modified the original game files, given the specific set of RPFs that is modified.
