Filming on Man Who Fell to Earth began May13,2021
Filming of Picard Season 3 coincided with Picard Season 2 and was begun February 16 2021 but the bill was filmed between then and March 8 2022
Kurtzman was show runner and EP on Man who fell to Earth. He was busy making that show the best it could be. Matalas was running and in charge of Picard Season 3. Not sure why you can’t believe what multiple sources can confirm
Also in the link provided is a quote from Kurtzman where he says he was against bringing the legacy characters back at first. Matalas convinced him.
Now I’ll be waiting for that apology but I expect it won’t come.
