Bug report

Given a non-python shebang line, e.g. #!/usr/bin/env bash, py.exe falls over with

❯ py ./x.py Unable to create process using '/usr/bin/env bash ./x.py' 

py.exe should not be trying to interpret non-python shebang lines on Windows. If py has been invoked (especially if manually invoked rather than implicitly by ftype association), the intent is to interpret the file as a python script.

I originally hit this with rust-lang/rust's x.py script, which is currently using /usr/bin/env bash to attempt to launch Python 3 across all OSes, whether they provide a python executable or just python3. (MSYS makes this more fun, as it does directly interpret and use the shebang line, rather than calling the ftype registered handler.)
