Yogg-Saron, Unleashed. Deck Summon Game crash

I played Yogg-saron, unleashed, bounced him back to my hand with shadowstep, then played shift gear putting him back into my deck. The next turn I play a chaotic tendril that casts the paladin spell Front Lines. In that spell cast my Yogg-Saron was summoned and was unable to be interacted with. I couldnt use the Titan abilities, I couldn’t target it, I couldn’t even hover over it. I take the rest of my turn, Throwing the match as I couldn’t use my Titan. Then my opponent starts their turn and halfway through their turn my game crashes. After rejoining the game my Yogg is interactable just in time for the opponent to kill me…
