Pandas version checks
-
[x] I have checked that this issue has not already been reported.
-
[x] I have confirmed this bug exists on the latest version of pandas.
-
[x] I have confirmed this bug exists on the main branch of pandas.
Reproducible Example
import pandas as pd
from pathlib import Path
pd.options.future.infer_string = True # Only needed with 2.3.1
folder = Path.cwd()
files = pd.Series(["a.png", "b.png"])
folder / files[0] # This works
folder / files # This raises an exception
Issue Description
The / operator with Path works fine with 2.3.1 with strings being object dtype, but not with arrow strings. The last statement produces this stacktrace:
Traceback (most recent call last):

While the error says something about Windows, a similar error occurs in Linux.
