Can't join coop game

[Teras Outis]

me and my friend have both completed the start of the game and have a garage, the invite to game/join game buttons in steam friend list aren't doing anything, regardless of who is hosting and or if the game is private/public

The host should have an invite code. If he sents you that code, you can join him.

The join code can be found by the host:

press escape, go to 'manage party' - the code can be found top left. If it doesn't work, make sure all of you have crossplay enabled in your settings.

We had this problem, too.
In our case, a restart of the game and the MP-Session was helpful.
After that, you have to invite him via ESCAPE, Manage Party, Invite (you can click on the empty picture next to yours, then the Steam overlay will open and you can invite

Also curious, my buddy has the code but I don't see where I can type that in. "Join Coop Game" just puts me in some random person's server

Is either of you set to Invisible mode? I had an issue where my friend could not invite me while I was set to Invisible mode.
