this is my version and I have installed “nightly-x86_64-pc-windows-msvc'

\leaf-ffi> rustc --version rustc 1.56.0-nightly (29ef6cf16 2021-08-31) \leaf-ffi> rustup toolchain add nightly info: syncing channel updates for 'nightly-x86_64-pc-windows-msvc'

Seems like recent changes of libstd broke UWP targets. Before we start to look into it, please try the nightly toolchain on 2021-08-13, which is the one I am using.

rustup toolchain install nightly-2021-08-13

[mikexxma]

rustup toolchain install nightly-2021-08-13

it works fine thks

Given https://github.com/rust-lang/rust/pull/88587 has been merged and building libstd no longer fails since toolchain nightly-2021-09-24, I will close this issue. Feel free to open another one in case build fails again.
