Might be the white space in the folder name? Try
pyversion("C:\Users\ASUS\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Python 3.11\python.exe")
pyversion('C:\Users\ASUS\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Python 3.11\python.exe')
By the way, it is recommended to use pyenv

Hi Fangjun Jiang,
Thank you for your comment!
By using
pyversion("C:\Users\ASUS\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Python 3.11\python.exe")
it gives an error like:
Error using pyversion
Path argument does not specify a valid executable.
And after that when when we are using pyenv instead of pyversion, it also gives error
pyenv('C:\Users\ASUS\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Python 3.11\python.exe')
Error using pyenv
Invalid number of arguments.

If you look at the file under C:\Users\ASUS\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Python 3.11\, they are most likely "short cut" file, not executable. Please locate the actual .exe file.

Hi Mukesh
The pyversion command is no longer recommended. See the doc at (Not recommended) Change default version of Python interpreter - MATLAB pyversion - MathWorks United Kingdom.
It is better to use pyenv instead Change default environment of Python interpreter - MATLAB pyenv - MathWorks United Kingdom
Try this
pyenv(Version="C:\Users\ASUS\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Python 3.11\python.exe")

Hi Mike Croucher'
Thank you for your comment! I appreciate your insight and perspective.
But I tried as your comments such as: pyenv(Version="C:\Users\ASUS\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Python 3.11\python.exe")
it gives an error like:
Error using pyenv
Path argument does not specify a valid executable.
Could you please provide any additional insights or suggestions on resolving this issue?
