Can't reproduce, try upgrading rust since your last nightly upgrade was 2022-11-11. Run rustup update (or rustup update nightly to be specific)

[upalchowdhury]

updating to lates solved the issue thanks.

[upalchowdhury]

rustup update nightly resolved the issue. Thanks @refcell

[refcell]

Great! Glad that worked!

[ncitron]

Yeah this error was due to rust-lang/rust#104238 which effected the nightly compiler for a little less than a week.
