`No such file or directory:` ruff. but file exists

Question

I am using nixOS and I have a flake.nix. I use pre-commit to run ruff.

my pre-commit config:

-   repo: https://github.com/astral-sh/ruff-pre-commit
    rev: v0.3.4
    hooks:
    -   id: ruff
        alias: autoformat
        args: [--fix]

Now when committing .py files I get this error:

[Errno 2] No such file or directory: '/home/{username}/.cache/pre-commit/repoo90awvpu/py_env-python3.11/bin/ruff'

But the file exists! I checked it. My ls command (with a full path) gives me:

.rwxr-xr-x 23M {username} 28 Mär 00:26 /home/{username}/.cache/pre-commit/repoo90awvpu/py_env-python3.11/bin/ruff

file outputs:

> file ruff
ruff: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=5703233b90c05154cbdd5c3f44975b02579aad23, for GNU/Linux 2.6.32, stripped

Does anyone know why I get the error, that my file does not exists, when it actually exists and is executable.
