Vision didn't get nerfed in Infinity War. he let himself die in Wakanda because letting Ultron take the wheel against Thanos would have created Infinity Ultron. go back and watch the woods scene at the end of Age of Ultron. VisionQuest just confirmed Vision never destroyed that last Ultron bot when the screen flashed yellow. he felt bad wiping out the only other being like him, so he secretly downloaded Ultron into his own head and spent the next three years keeping him locked in a mental cage. in episode 4 of VisionQuest, the second Vision is losing a fight and agrees to let Ultron take the wheel to survive, Ultron immediately hijacks his vibranium body and locks Vision out of his own controls. that means when Corvus Glaive stabbed him and Thanos was walking toward him in Wakanda, James Spader's Ultron was wide awake inside Vision's head screaming at him to hand over control. Vision begged Wanda to destroy the Mind Stone because he knew if he let Ultron out to beat Thanos, Ultron would take the 5 stones for himself just like he did in What If.
