vs code install rls as :

Executing task: rustup component add rust-analysis --toolchain stable-x86_64-pc-windows-msvc <

info: component 'rust-analysis' for target 'x86_64-pc-windows-msvc' is up to date
error: component 'rust-src' for target 'x86_64-pc-windows-msvc' is unavailable for download for channel stable
exit code: 1

Executing task: rustup component add rust-src --toolchain stable-x86_64-pc-windows-msvc <

error: component 'rust-src' for target 'x86_64-pc-windows-msvc' is unavailable for download for channel stable
exit code: 1

This is a bug in how profiles work in 1.20 when installing the complete profile. If you rustup component uninstall rust-src and then rustup component install rust-src it'll be fixed.

[itfunly]

@kinnison yes, you are right.

[kinnison]

Cool, I'm glad that worked for you. I'll endeavour to ensure that the next rustup release can cope with the snafu :D

[kinnison]

I believe that #2115 ought to fix this.
