Cant't create a Venv on Debian - No error message

I had my files transferred on another OS (from RetroPi to Debian) and I wanted to relaunch my Venv. I started by deleting the .venv folder I had (which was not that easy as some files were protected and this might have been my mistake). * Then

install venv

which worked perfectly. * And when I try to run

-sh
    (sudo) python3 -m venv .venv

it runs for a few seconds, doesn't give any message and doesn't create the .venv file or nothing. * Having sudo or not in the command doesn't change anything. * I tried changing permissions of the folder

-sh
    chmod 777 folder_name

but same result. The fact that I have no error message makes me unable to do precise research and I'm a newbie regarding Linux.
