I tried to boot into the previouse kernel and downgrading wpa_supplicant first, which did not help. So I suspected some change in NetworkManager to be responsible. After trying some other configuration changes I compared the log output from a machine that was not yet upgraded to that of an upgraded one, and the difference was that the latter changed the mac address between scanning and connecting. So I tried to disable this behaviour, and it worked after that. My other wifi devices too work with mac address randomization turned on, just this one does not. Maybe it has to do with the timing between chaning mac addresses and initiating a connection, I really have no idea what the root cause could exactly be.
