But I get the errors

Any solution to this? I have tried uninstalling and reinstalling it, but I haven't installed in the first place. Nothing works. I have Python 3.10 installed on macOS Monterey.

Like mentioned here: https://stackoverflow.com/a/70651438/13526701 There currently is no support for pyqt5 for python3.10. Try going back to a version that is supported, or attempt to install a version from elsewhere, be careful though who you trust.
