So I am having this problem over and over again https://gyazo.com/c5e50a6b08fe37bffe1732914233cb2f 
Can’t find a fix in the forum for this.
GTA V version? Latest version
Up to date? Yes
Legit or Pirate copy? Legit
Steam/CD/Social Club? Steam
Windows version? W10
Did you try to disable/uninstall your Anti-virus? Yes it’s disabled for the folder where FIVEM is running
Try and reinstall fivem
Same error -_- i tried all the solutions
Tried already, no can do…
i found a way to fix it on my computer , i had disable my anti-virus and go in quarantine for restaure all the file from fivem who have been falsy detect as dangerous item.
after restaure every files and my anti-virus put off , it work again ^^
So I did what you said that fixed the problem for you, but I got the same error.
This is what extracts before giving the error 
And this is what is inside the FiveM.app folder 
I still don’t have a clue of what’s wrong. And it’s strange that a lot of people have the same error, but there is no fix explained on the forum
you didn’t recover all the files , that why you have only few files in your fiveM folder,
Check closer on your anti-virus for recover all the dangerous and suspect files link with fivem , after recovered all , you should see more files in your fivem folder.
Oops i ´ve already deleted m’y files un quarantine
Sorry but the only file I had on the anti virus quarantine was CitizenFX.exe.tmp
I found the fix. If anybody has this issue, just follow the link provided (https://runtime.fivem.net/client/prod/bootstrap/CitizenFX.exe.xz) and insert the file into your FiveM App Data Folder.
Update: NVM doesn’t work
Update 2: Found a temporary fix. Redownload the FiveM.exe and put it in a new folder and launch it. It should launch like normal.
For me don’t put the installer FiveM.exe on network drive not working…
ok on local drive
