Python • How to use different versions of Python?

Hello, I installed tensorflow lite on my rp5 but it gave errors. I read that tf lite doesn't work on 3.11 and I have to downgrade to Python 3.9.

When i select Python 3.9 on Thonny, it gives this error:

INTERNAL ERROR, got '' instead of 'OK'

During handling of the above exception, another exception occurred:

Process ended with exit code 1.

Tried this but didn't work: sudo apt-get install libffi-dev

I am new to linux and raspberry, thank you for your time.
