[yoganandc]

looked at CI and saw that it passed with channel = "nightly-2022-02-08". I did

rustup install nightly-2022-02-08
rustup component add rust-src --toolchain nightly-2022-02-08-aarch64-apple-darwin
rustup default nightly-2022-02-08

verified that everything builds with that version.

I'll fix soon, thanks for reporting.

Seems they fixed something as CI works again. Maybe this one: rust-lang/rust#94088
