use_python() throws "Error in python_config_impl(python)" in Windows 10 for Python 3.12.0

[shivam7898]

Python 3.12.0 was installed from www.python.org in Windows 10.

library(reticulate)

#Python 3.12 exists at the location shown below in windows 10
normalizePath(Sys.which("python"))
#[1] "C:\\Softwares\\Python\\Python312\\python.exe"

#Python directory exists in Windows PATH also
strsplit(Sys.getenv("PATH"),";")[[1]][14:15]
#[1] "C:\\Softwares\\Python\\Python312\\Scripts\\" "C:\\Softwares\\Python\\Python312\\" 

#Python Version
invisible(system('python --version'))
#Python 3.12.0

Following command used to work with previous Python 3.11 but does not work with the Python 3.12. Past working example can be seen Here. Additionally, This Issue seems to show a similar but different error and I tried using the path with or without python.exe but the error remains.

use_python("C:\\Softwares\\Python\\Python312\\python.exe")
#Error in python_config_impl(python) : 
#  Error 1 occurred running C:/Softwares/Python/Python312/python.exe: 
#In addition: Warning message:
#In system2(command = python, args = shQuote(script), stdout = TRUE,  :
#  running command '"C:/Softwares/Python/Python312/python.exe" "C:/Softwares/R/LibFiles/reticulate/config/config.py"' had status 1

py_config()
#Error in stop_no_virtualenv_starter(version = version, python = python) : 
#  Suitable Python installation for creating a venv not found.
#Please install Python with one of following methods:
#- https://www.python.org/downloads/
#- reticulate::install_python(version = '<version>')

To be frank, I have been away from the system for more than 6 months and had to update all including R, RStudio, and Python. So, please forgive me if the problem is not related to reticulate. Thanks for an awesome package and closing the issues I opened previously :)

Update to confirm that reticulate_1.32.0 works with python 3.11.6. As shown below, now py_config() can find both versions of python installed in the system but it is still unable to use python 3.12.0.

py_config()
#python:         C:/Softwares/Python/Python3116/python.exe
#libpython:      C:/Softwares/Python/Python3116/python311.dll

Thanks for reporting, this is now fixed in the dev version of reticulate.
