cargo new <packagename> on Windows 10 will not cargo run: "error: Access is denied. (os error 5)"

Problem

Generating a new project with Cargo makes a project that is not runnable on Microsoft Windows 10 Pro.

Steps

1. Following the Getting Started instructions on the website, install Rust by downloading and running rustup-init.exe (64-bit installer).
2. Open the Windows Terminal (press the Windows button, type "command prompt" and hit Enter).
3. Verify the installation worked with cargo --version (it reports cargo 1.60.0 (d1fd9fe2c 2022-03-01)).
4. Enter the commands listed in the instructions: cargo new <packagename>, cd <packagename>, and then cargo run.

Note that it outputs:

error: Access is denied. (os error 5)

Possible Solution(s)

As a new user of Rust and Cargo, the error message is opaque and there is not much direction as what can be done next to fix this.

Thanks for the report! The error message always gets rooms to improve.

Could you run cargo run --verbose to see if we could narrow it down? Perhaps setting an environment variable set CARGO_LOG=debug to print the logs would be better if you can.

Thank you for your comment :)
Strangely, I cannot reproduce this issue anymore (cargo run now succeeds after the same instructions of step 2-4). Perhaps I have since restarted the computer and that fixed something. Perhaps it is something that occurs on first install but disappears after a restart? There is no issue with space on my hard drive or anything like that.

Got it. Thank you!
I am going to close this issue to reduce our already-exploding issue lists 😆. If you find any possible cause or a way to reproduce it, feel free to reopen.
