yfinance refusing to work when import as yf

问题

I'm trying to get started with yfinance for python, however, I can't seem to get a simple command to work for it.

import yfinance as yf

msft = yf.Ticker("MSFT")

print(msft.info)

hist = msft.history(period="5d")

When i try to run this it give me a whole bunch of errors I don't understand. The following errors below is only about one fifth of the actual errors, and I'm sure mods wouldn't be happy if I pasted it all in, I'm sure you get the point.
