If you have a spare antenna I would cut it and expose the center conductor, connect it to the board and ensure you have continuity (this is simply to verify the issue is not with the connector board side, mishapen etc) to the component/s in the general area.
Now, the antenna go off to what looks like a precision resistor package, but it’s highly likely that’s not actually what this component is as I haven’t yet looked into them, but they’re a 6-pin package, white and black and have an “S” printed on them, it’s possible if this component was open or had failed in someway that this is your problem.
If you have a known good board, I would verify that this 6-pin package tests the same as that
I’ve never encountered a situation where a bad WIFI/BT IC would cause your symptoms, if it was a bad IC then it would either not work at all or you’d get the orange screen. The symtoms are more inline with not having the antenna connected
