Do you have the toolchain for the declared rust-toolchain.toml installed? If you remove the toolchain file from the repo, does it still happen?

Sorry for the Late reply. Turns out I forgot to install the rust-toolchain.toml. Sorry for the waste of time.

@homebrewmellow the project has a rust-toolchain.toml file. if you don't have the version of rust in the rust-toolchain.toml installed it won't work.
