error[E0554]: `#![feature]` may not be used on the stable release channel
   --> C:\Users\_\.cargo\registry\src\github.com-1ecc6299db9ec823\anyhow-1.0.60\src\lib.rs:214:32

This seems to be a recent issue in anyhow dtolnay/anyhow#250
Anyhow tries to enable the backtrace feature in its build.rs file if the current toolchain supports it, but it seems like that detection has gone wrong somehow.

[jakobhellermann]

We can either wait for a fix in anyhow or maybe depend on a specific anyhow where the problem doesn't occur (if there exists such a version).

[tguichaoua]

Fixed with cargo clean, I think it was due to the update of the toolchain.
