Show your config? And also the version variable line in the file you are targeting

[foxmask]

What config do you need I show you ?

And also the version variable line in the file you are targeting
what do you mean ?

I've just run hatch from a venv

in the meantime my setup changed as I have to change of linux distrib

now I have hatch 1.9.1 and python 3.11.2

[foxmask]

it looks like we use hatch shell as if we do source bin/activate inside a venv

So the issue should not appear if we use hatch "correctly" and not after activated a venv ;)
