If you can’t start the game at all

Did you try to disable/uninstall your Anti-virus? - I have got only Windows Defender, tried to disable Firewall.

Important parts

What is the issue you’re having? - FiveM doesn’t want to open by an unknown error.
What are you trying to do? - To run it.

What have you tried already to fix the issue?

• for FiveM, only some reinstall, nothing that much.

That’s what I did it for Rockstar Games/Social Club to join into GTA Online but still doesn’t work either.

Deleted save files from documents, also Rockstar Games/Social Club Launcher, every Rockstar contains. Added on Windows Defender Firewall those ports (Inbound): 6672, 61455, 61456, 61457, 61458. What I’ve noticed, when loading online and going to home button at social in-game, saw that Network Information appears at NAT Type: Detection Failed. UDP may be blocked.
That’s it could be why doesn’t work to launch also FiveM? Because, it blocks something from the network or I don’t know what to think/say.

SCREENSHOTS

1. • FiveM
     2 & 3. JOINING GTA V ONLINE

**What did you do to get this issue? - Nothing, just after an fresh install of GTA V and FiveM.

What server did you get this issue on? Be specific and name some, ‘all of them’ by itself isn’t useful! - Didn’t make it that far.

An reply update about this,

What I did to relaunch FiveM and also working GTA Online by switching with another internet connection. After, when I was running FiveM, I plugged back the main ethernet cable, seems good atm. and that’s all you need.
