a bit new in MultiversX building.
Using WSL2 on Windows, and rustc version is:
:~/multiversx/smart_contracts/crowdfunding$ rustc -V rustc 1.70.0 (90c541806 2023-05-31)
All this tools are new for me. I am following the Crowdfunding tutorial (https://docs.multiversx.com/developers/tutorials/crowdfunding-p1/). When it comes to build the contract, I get the issue:
~/multiversx/smart_contracts/crowdfunding$ mxpy contract build

As it says

Feature attributes are only allowed on the nightly release channel. Stable or
beta compilers will not comply.
Erroneous code example:
``
#![feature(lang_items)] // error: `#![feature]` may not be used on the
// stable release channel
``
If you need the feature, make sure to use a nightly release of the compiler
(but be warned that the feature may be removed or altered in the future).
I tried to install the nightly version according to https://github.com/casbin/casbin-rs/issues/215
rustup install nightly
Do you have any idea to help me? Thanks a lot
--[EDIT] For those who have the same issue:
Try mxpy contract build --no-wasm-opt Instead of mxpy contract build
