Hello. So basically, this has happened 20 times before, and I have reinstalled each time.

I go to play GTA 5 on Steam, and everything is good, it takes me to the rockstar launcher, but either the play on steam button just keeps canceling, or it works for a second, and cancels.
I am running a fresh, unmodded GTA and I just hope somebody can help me. I can run FiveM fine, but nothing else. I currently uninstalled all things that can access it for the moment though, like Fivem, ETC.

I tried to make a new fivem test server but when i click the FXServer it says like "Could not load component manifest vfs-core.dll"

plus ive reinstalled it 13 times.

Okay so I used to mod before this. I didn't play it for a while and when I got back, it didn't work.
I can launch it and the Rockstar launcher will launch but it will say starting but then cancels the start.

Update: I have figured out it's not just GTAV, It's a few of my games on steam, but does anybody still know any fixes for the steam bug?

I appreciate everybody's help, I'm going to try every fix.

So I reinstalled Gta 5 on Steam after doing a clean wipe, and when i try to start it, rockstar launcher opens and sayings starting GTA 5 but then stops and reverts, can anybody help.
