Wow!
Remove Q11 and measure again. Somewhere there's an unrecognized conduction path. Poke around with meter to try finding it. Solder splash/solder bridge? Open PCB trace? Eg.there should be about 1.2V between Q38 emitter and Q11 base--- established by D18+D22. But you're observing more drop than that. Has to be some cause/explanation...
