``` query stack during panic: #0 [analysis] running analysis passes on this crate end of query stack ```

Strangely this worked after a cargo clean whilst I was trying to produce a minimal test case so I can no longer reproduce.

[Aaron1011]

This should be fixed on the latest Nightly.

[campbellC]

Yup confirmed that on both the latest beta and nightly I didn’t see the error.

[Aaron1011]

Note that this is an incremental compilation issue - if it wasn't fixed, it could take several edit-compilr cycles to show up. However, this particular issue was fixed by #91924
