I've compared your shebang (#!) statement's hex dump to an identical
(working) one on my system. I found no differences.

0. I've done some searching about this. I think it is down to you storing
your scripts on a NAS drive. Can you copy a script from the NAS drive and
see if it will run OK from a local drive's directory? This webpage might be
of interest: https://github.com/microsoft/WSL/issues/2969 . I think the NAS
drive might be mounting as "noexec"

Failing that, here are some other ideas...

1. What is the output of:
which python3

2. When you run test.py, and get the Input/Output error, what is the output
of this command:
echo $?

3. Try this as a script and see if it works:
#!/usr/bin/env python3
print ("Hello")

4, Try this - it should get you into the python command line:
$ env --debug python3

HTH,


Ian
