Broken Conda Installation After Conda Update Python

I have tried upgrading Python version on a Miniconda installation by running conda update python. The version was being taken from 3.8 to 3.10. This seems to have broken the installation. No matter what command I run, I get the following:
➜ project conda activate
Traceback (most recent call last):
File "/home/user/miniconda3/lib/python3.10/site-packages/conda/common/serialize.py", line 13, in <module>
import ruamel_yaml as yaml

During handling of the above exception, another exception occurred:

Help on fixing this is appreciated.

Spyder will not launch

For some reason Spyder is not launching when I try to start the application. I tried to then run it through the console, but run into this error:
(base) C:\>spyder
Traceback (most recent call last):
File "C:\Python\Anaconda3\lib\site-packages\qtpy\__init__.py", line 210, in <module>

I've tried running
pip3 install pyqt5
but I get the same error after this installation is completed when I try to launch Spyder through the console. Any advice on this issue?
Can also mention that I tried to download PySide, but couldn't complete the installation as some other errors appeared.

Anaconda: ModuleNotFoundError: No module named 'PySide'

I'm having trouble with Anaconda Navigator. The program isn't lauching anymore, I think it happened after I shutdown my Windows 11 and forced the program to close. When I try to launch it in the Anaconda Prompt, I have the following lines of errors:
(base) C:\Users\user>anaconda-navigator
Traceback (most recent call last):
File "C:\Users\user\anaconda3\lib\site-packages\qtpy\__init__.py", line 209, in <module>

raise PythonQtError('No Qt bindings could be found')
qtpy.PythonQtError: No Qt bindings could be found
I've tried solutions in Stackoverflow and already reinstalled the program, but nothing worked yet. If anyone can help, I will appreciate very much!
EDIT: The program returned to normal alone, don't know what happened.

The first error looks like you are missing the pyside module. Can you run
conda install PySide
or
pip install PySide
and see if this fixed that error?

Unable to start the spyder IDE

I have created an environment in Anaconda using environment.yml file. After activating the environment when I try to open Spyder IDE it shows up the following error message.

I am unable to sort it out using all previous suggested solutions on using other gcc versions.
Thanks in advance.
