Pandas version checks

  • I have checked that this issue has not already been reported.

  • I have confirmed this bug exists on the latest version of pandas.

  • I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

import pandas as pd
from pathlib import Path

home = Path("~/").expanduser()
suff1 = pd.Series(["a", "b"])
suff2 = pd.Series(["c", "d"])
home / suff1 / suff2

>> ArrowInvalid: Could not convert PosixPath('.../a') with type PosixPath: did not recognize Python value type when inferring an Arrow data type

Issue Description

While home / suff1 and home / suff1 / suff2.astype('O') works correctly

Expected Behavior

Expected behaviour is the same as for the following code

import pandas as pd
from pathlib import Path

home = Path("~/").expanduser()
suff1 = pd.Series(["a", "b"])
suff2 = pd.Series(["c", "d"])
home / suff1 / suff2.astype('O')
