[Fixed] Party failed to start [Network error 450]

Since the Eco Update, I’ve been able to host and attend my own party. When I click on host party, my game icrashes. When I reopen the game, it allows me to start another party as if I never started one. However, my friends say they can see my party, attend it, sticker, interact, etc.. It would be nice if I can actually attend my own party!!
