I’m pretty new to platformio and the ESP32. I have a project where it was working fine before, and then all of a sudden when I opened it, it’s giving the following error when compiling during the build of the espidf dependencies:
error: can't find Rust compiler
If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.
To update pip, run:
pip install --upgrade pip
and then retry package installation.
If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.
This package requires Rust >=1.56.0.

Failed to build cryptography
Could not build wheels for cryptography which use PEP 517 and cannot be installed directly
You are using pip version 19.0.3, however version 23.2.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
I’ve tried to upgrade pip but the version used when recompiling seems to always be 19.0.3 despite the pip version being 23.2.1. I’ve also tried just installing cryptography and it seems to install fine.
Rebuilding the project resulted in the same error message. I did notice that the error message indicated that the platform was Windows 10. I am currently using Windows 11. Does that affect anything?

If you are seeing a compilation error please try the following steps to
successfully install cryptography:
1) Upgrade to the latest pip and try again. This will fix errors for most
users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
2) Read https://cryptography.io/en/latest/installation/ for specific
instructions for your platform.
3) Check our frequently asked questions for more information:
https://cryptography.io/en/latest/faq/
4) Ensure you have a recent Rust toolchain installed:
https://cryptography.io/en/latest/installation/#rust
Python: 3.7.4
platform: Windows-10-10.0.22621-SP0
pip: n/a
setuptools: 68.0.0
setuptools_rust: 1.7.0
