unresolved-proc-macro error on all proc macro usages #11150

I've verified that proc macro support is enabled by looking at the client logs:

However, I'm still getting the unresolved-proc-macro error that macros are not being expanded. Is there something else that has to be enabled or installed to turn this on? The User Manual doesn't mention anything else. It does say "can also indicate project setup problems" but doesn't indicate what those might be.
