Need help with workshop addon

I don’t know if this is the right place to ask this but here I go anyway.

I have this problem when I try to upload my addon to the gmod workshop

Setting breakpad minidump AppID = 4000
Steam_SetMinidumpSteamID: Caching Steam ID: 76561198055006648 [API loaded no]

Does anyone know why this is happening I API loaded my profile.

Kindest regards,
Jeromy Han

What are you using to upload?

This isn’t a letter to King Henry the 3rd

And you should check out this page for a tutorial.

This is what it says

Couldn’t open the icon!

Your addon must have a relevant icon.

It does it’s also 512x512

The error message clearly suggests that you are not giving the problem a path to the icon, or that the path is invalid.
