the anaconda navigator dose not open

[bluesky66]

I tried a lot but I get the below error. I did many solutions but did not work. Thanks

below is the error:

(base) C:\Users\mohammze>anaconda-navigator
Traceback (most recent call last):
File "C:\Users\mohammze\Anaconda3\lib\site-packages\qtpy_init_.py", line 204, in
from PySide import version as PYSIDE_VERSION # analysis:ignore
ModuleNotFoundError: No module named 'PySide'

During handling of the above exception, another exception occurred:

This is not a quamash issue, looks more like a conda issue.
