I've attempted to diagnose it by loading the library directly as follows:
```
> library(arrow)
...
> reticulate::repl_python()
Python 3.12.2 (C:/Program Files/Python312/python.exe)
Reticulate 1.35.0 REPL -- A Python interpreter in R.
Enter 'exit' or 'quit' to exit the REPL and return to R.
>>> import ctypes as c
>>> dll = c.WinDLL(r'C:\Program
Files\Python312\Lib\site-packages\pyarrow\lib.cp312-win_amd64.pyd')
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "C:\PROGRA~1\PYTHON~2\Lib\ctypes\__init__.py", line 379, in __init__
self._handle = _dlopen(self._name, mode)
^^^^^^^^^^^^^^^^^^^^^^^^^
OSError: [WinError 127] The specified procedure could not be found
```
That produces a pop up with the mangled C++ symbol name that caused the
issues, in this case eg: "The procedure entry point
?type@StringBuilder@arrow@@UEBA?AV?$shared_ptr@VDataType@arrow@@@std@@XZ could
not be located in the dynamic link library C:\Program
Files\Python312\Lib\site-packages\pyarrow\lib.cp312-win_amd64.pyd".
If I repeat the above without first loading the R arrow package, it will
load the python libs just fine. Is this problem caused by both the R and python
packages having different "arrow.dll" files that they're attempting to load
into the same address space?
