If an issue with starting:
GTA V folder screenshot
GTA V/update/x64/dlcpacks screenshot
Filepath to FiveM folder
FiveM client folder screenshot
Which antivirus/firewall software are you using?
Did you try to disable/uninstall your Anti-virus?

Also add what you already tried so far.
Connecting to servers only work when using direct connect method with console, other than that it’s impossible to connect to any server. Additional which only happens in FiveM only but no other game is consecutive Connection Interrupt every 5 minutes or so, which i guess is caused by packet loss but I got no packet loss in any other game. Reinstalling clean FiveM files and deleting cache didn’t help.
