The stack reference is a red herring. I removed all of them and it now gets stuck saying:
```     pulumi:pulumi:Stack      tlayen-deployments-prod  running..```

Unsurprisingly it was a PEBKAC. Somehow an `Sequence[Output[str]]` was actually an `Output[str]`` and unpacking that with `*` seems to cause a hang. No idea what it's doing.
