Describe the bug

If a rust folder contains rust-toolchain.toml requiring version that isn't installed, rustc --version automatically tries to install the toolchain. So if we quickly open nvim or any other cli program after switching to the folder, contents from stderr is displayed.

Steps to reproduce

1. Create empty rust project with cargo init
2. Create rust-toolchain.toml file with content as follows:
   [toolchain]
# set channel to one that is not installed
channel = "1.72"
3. Switch to the directory and open any CLI program like nvim or top.
