Fatal Startup Error for python's MATLAB engine

I am trying to call MATLAB from python.

I have python 3.9.13 and matlab 9.11.0.1769968 (R2021b).

I installed the matlab engine for python by running the following commands in matlab:

cd (fullfile(matlabroot,'extern','engines','python'))

system('python setup.py install')

I then ran the python commands:

>>> import matlab.engine

>>> eng = matlab.engine.start_matlab()

Traceback (most recent call last):

File "<stdin>", line 1, in <module>

File "MY_USER_FOLDER\AppData\Local\Programs\Python\Python39\lib\site-packages\matlab\engine\__init__.py", line 130, in start_matlab

eng = future.result()

File "MY_USER_FOLDER\AppData\Local\Programs\Python\Python39\lib\site-packages\matlab\engine\futureresult.py", line 67, in result

return self.__future.result(timeout)

File "MY_USER_FOLDER\AppData\Local\Programs\Python\Python39\lib\site-packages\matlab\engine\matlabfuture.py", line 87, in result

handle = pythonengine.getMATLAB(self._future)

matlab.engine.EngineError: Unable to launch Simple server: Unable to launch C:\Program Files\MATLAB\R2021b\bin\win64\MATLAB.exe

because: Timed out reading transport byte from transport

And the matlab error:

Fatal Startup Error

Dynamic exception type: class

foundation::catapult::carrier::stream::TranspodException

std::exception::what: Unable to conned to parent because:

Try installing using the "python -m pip install ." command instead.
