Problem description

Failed to build project with this message:

error[E0554]: `#![feature]` may not be used on the stable release channel
   --> C:\Users\kaede\scoop\persist\rustup-msvc\.cargo\registry\src\github.com-1ecc6299db9ec823\anyhow-1.0.68\src\lib.rs:214:32
    |
214 | #![cfg_attr(backtrace, feature(error_generic_member_access, provide_any))]
    |                                ^^^^^^^^^^^^^^^^^^^^^^^^^^^

Steps to reproduce

1. Create a new project.
2. Add anyhow = "1.0.68" to dependencies. Do not push build button yet.
3. Push sync button.
4. Build the project.

After step 4, cargo build always fails. For workaround, remove /target/ and type cargo build from a terminal.

Maybe rust-lang/rust-analyzer#12973, dtolnay/anyhow#250 and dtolnay/anyhow#288 are related issue.

#9198 may be not fully resolved or en-bugged.
