Errno 13 Permission denied when pip upgrade or pip install

I have set up my virtual ennvironment and i'm trying to install the package but i keep on running into this error :

: Could not install packages due to an OSError: [Errno 13] Permission denied: '/home/daeltam/.MyVenv/lib/python3.11/site-packages/propcache' Check the permissions.

This happens when i run : -

-m pip install discord

-

install discord --user

-

install discord

All of those tests have been made looking at forums. But the majority of them advice to create a virtualenv to fix this, which is already the case for me... Running

sudo pip install --upgrade pip

only gives me this error message i can't understand, no matter if i'm inside the venv or not :

: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
    python3-xyz, where xyz is the package you are trying to
    install.

    If you wish to install a non-Debian-packaged Python package,
    create a virtual environment using python3 -m venv path/to/venv.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
    sure you have python3-full installed.

    If you wish to install a non-Debian packaged Python application,
    it may be easiest to use pipx install xyz, which will manage a
    virtual environment for you. Make sure you have pipx installed.

    See /usr/share/doc/python3.11/README.venv for more information.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification

I am on debian if this is useful, i'm a newbie regarding linux and permissions are still a little bit obscure for me even after reading articles to understand. **Edit with my progress :** As below comments and answers seem to say, the problem might have been me setting up my venv with sudo during one of my tests. So what i just tried is deleting the venv ( with sudo rm -rf .venv) and then creating one back with python3 -m venv .MyVenv (i prefer that name) But i got this error message once again : Error: [Errno 13] Permission denied: '/home/daeltam/Daeltam/.MyVenv/pyvenv.cfg' I can still activate the Venv with source Path/bin/activate but i haven't made more tests.
