Any one has faced same issue before on Windows 10?

Answer 1

I was running into the same issue. The way I solved it was by manually reinstalling the stable-x86_64-pc-windows-msvc toolchain which apparently got corrupted while installing.

I did:

rustup toolchain remove stable-x86_64-pc-windows-msvc

Then:

rustup install stable-x86_64-pc-windows-msvc

Some notes:

• You can get the toolchain name (they're divided by their release channel: stable, nightly, beta) by navigating to your user folder and finding the .rustup folder (E.g: C:Users\MyWindowsUser\.rustup\toolchains)
• This should also fix the RLS extension for VSCode.
