Check your firewall

Does the script crash or it's just an empty menu?

Is there a GTACOOP.log in the scripts folder?

Well post it then

That's not GTACOOP.log, that's GTACOOPSettings.xml

It's not missing. Try going to http://46.101.1.92/ and connect to any of the servers.

The settings file gets created automatically. Make sure you've got an updated scripthookvdotnet

For coop you can use natives to achieve this. Coop doesn't support client-side scripts.

That means ScriptHookVDotNet isn´t working. Check their thread on gtaforums or their github page. https://github.com/crosire/scripthookvdotnet

I've heard having more than one GTAV game on the disk can cause this issue
