Street Sampler issue for party play (co-op is STILL unplayable...)

This happens with far more missions than just this one and seemingly at random, but it has now happened twice in a row for the line challenge "Street Sampler" in Market Mile.

While playing in two player co-op, the leader starts a mission and one of the party members will not be pulled into the mission leaving them in a soft locked state. The player that does get pulled in also gets stuck in a "Waiting for Players" screen.

For the player who gets left behind, no button inputs work. If the player who does get pulled into the mission isn't the party leader, they get stuck unable to end the mission since they aren't the party leader. The only solution is for both players to force quit the game.

Platform: PC
Client: Steam

This has been an issue for weeks, and no matter how many Twitter posts they make, or surveys I fill out, I feel like my reports of game breaking bugs go completely unseen and unheard. Who cares about pants colors when you can't play MULTIPLAYER in a MULTIPLAYER game??
