I'm willing to buy this game but I had bad surprises before. (games that didn't support their coop anymore)

In the previous game he seemed a lot more reserved. In the very first mission of shards there's back to back pop culture references and quips. This Styx feels more like green deadpool than the edgy antisocial rebel goblin from akenash. At least the amazing voice actor recovers it a little....

Shadows or darkness?

The goblin will return someday bros...

We both already restarted our pc, the game, reinstalled and installed the game. He invited me multiple times and tried all the saves but to no avail. I also invited him myself as the host this time and tried existing saves, and even started a complete new game but again NOTHING is working. We're so frustrated cos we already tried literally everything. What are we missing? anyone knows advanced troubleshooting for this issue please?...
