Qtile crash on Python update (3.10) [Arch Linux]

I met this problem when I updated the whole system (Arch Linux) this morning. After restarting the computer, qtile just crashed. Here is the error message.

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

It seems like the Python update causes this, or I’ve missed something. Thanks in advance.

@elParaguayo Yes, I agree with you. I don’t clearly understand why the permissions changed after updating the system. @erlonbie You can do that by running chown commands like so: sudo chown [your-target-username] /path/to/the/files/that/threw/you/permission/error/messages. In my case, I ran these commands: sudo chown username /usr/lib/python3.10/site-packages/google_api_core-2.3.2-py3.10.egg-info/namespace_packages.txt and sudo chown username /usr/lib/python3.10/site-packages/google_api_core-2.3.2-py3.10.egg-info/PKG-INFO.

It worked! Thank you!
