Happens on multiple Ubuntu 24.04 workstations but not on any Windows 11 machines.
All machines are configured with the suggested fixes/settings per your emails for the Python Env extension, that seems to be doing well.

However...

Either from the hotkey or from the menus, when you run a Python file a CTRL-C is immediately issued. It is consistently intermittent, meaning, it's not 100% of the time but from observation it is 75-80% of the time. So, 8 out of 10 times you have to run the script again...and again... until it runs as expected. Sometimes you get lucky, and the CTRL-C is thrown to soon to interfere, like right before the venv is activated.

Thanks folks and cheers!
