Management Key won't generate on M1.

• YubiKey Manager (ykman) version: 1.2.4
• How was it installed?: Downloaded from yubico.com.
• Operating system and version: MacOS Monterey 12.0.1
• YubiKey model and version: YubiKey5C 5.2.7
• Bug description summary:
  Cannot create new Management Key in Yubikey Manager.

I was trying to create a new Management key, it kept giving me an error so I dug deeper and it looks like it's an architecture issue. It's saying a file is for arm64 when it needs x86_64. I'll put the logs below.

Hi,
It looks like it is not using the bundled Python. You can see this from the path /Users/username/Library/Python/3.9, which is your own local Python. I am not sure what has caused this. Perhaps there is a PYTHONPATH or PYTHONHOME variable set?
