Same problem here.

Having a Mac Pro 14 (M1 PRO) Anaconda first provided me with the old Mac installer (x64), and after installing it and it not working, I downloaded the correct installer, and when trying to install it I get the same error.

I find that the problems above can be solved by the solution below:python - How to solve error while installing pyqtwebengine - Stack Overflow

However, there is new problems after I input the codes suggested above as below when I tried to launch Anaconda Navigator:

Traceback (most recent call last):
File “/Users/user/opt/anaconda3/bin/anaconda-navigator”, line 7, in
from anaconda_navigator.app.main import main
File “/Users/user/opt/anaconda3/lib/python3.9/site-packages/anaconda_navigator/app/main.py”, line 19, in
from anaconda_navigator.app.start import start_app

File “/Users/user/opt/anaconda3/lib/python3.9/site-packages/qtpy/QtCore.py”, line 57, in
from PyQt5.QtCore import *
ModuleNotFoundError: No module named ‘PyQt5.QtCore’

also, there is still problem when I tried to launch Spyder:
Traceback (most recent call last):
File “/Users/user/opt/anaconda3/bin/spyder”, line 11, in
sys.exit(main())
File “/Users/user/opt/anaconda3/lib/python3.9/site-packages/spyder/app/start.py”, line 233, in main
