Or Quincy Zangetsu triggered by something Ichigo wasn't fully told of or hadn't tried. And he need to be fully healed of his injuries. Yhwach could have someone in front of him and he'll go "So, another one who will know true despair.", kills them, and takes their powers.

Another one would be "LOL, you think I would just let you use Bankai against me after that last time, Ichigo?" or "The dream is dead. Know my name and fear it. I am Yhwach."

Anyway, Ichigo may not have been at his strongest at all, if you think his full Quincy powers have been unused. Ichigo had used a lot of Shinigami abilities, and Hollow ones, but not a lot of Quincy type ones. I Think Uryu Will Jump Into The Fight, Either That Or Isshin/Ryuken.
