Panic while compiling on 1.75.0, aarch64-apple-darwin

[CinchBlue]

Overview

I cannot share details, but I was doing cargo test and cargo nextest on my codebase after a cargo sweep --time 10 and it had an error. Could this be due to incoherence of the cache?

Could this be due to incoherence of the cache?

That seems very likely.
