One thing I have not tried, yet seems viable, is instead of frequent 1:1's (which only really matter when there is a personal problem) is something similar to the Oxbridge Tutorial (small group of students sit with Professor and discuss problems at hand.)

I think this approach could hear fruit as it moves the discussion from "how are you feeling" and onto "let's have an open but focused discussion on the problems facing us - not writing code but thinking first and foremost"

When me or my teams think first, things always flow better.

It's rather an indictment of me that I miss it and want to try it again ...
