Ichigo hasn't lost any of his powers, ever. He just stopped using them for whatever reason. What he has lost is his reiryoku, but his powers and their natures are part of him and they can never be truly lost. The novel confirms that Ichigo regained his full powers days after Yhwach was defeated. Ichigo doesn't use his hollow powers after the HM arc even when he regains his reiryoku because there was never a need for it, he was always vastly overpowering his enemies with little effort, the only exception to this is Yhwach, but he never gave Ichigo an oportunity to bring out his mask in their first encounter, in their second encounter Ichigo was subconsciously holding back. In their third encounter Ichigo brought out the hollow fusion. Hell, the novel even confirms that Ichigo is the only person alive who can replace the king should his powers that support the universe be completely lost. Yhwach knew, Jugram knew and they both tried to avoid that possibility. Ichigo remains the strongest living being and the only person who Yhwach was cautious against.
