[Lerofni]

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 Polars.

Reproducible example

import polars as pl
from filelock import FileLock
import time



data = {
    "col1": [1,2,3],
    "col2": [4,5,6],
}
test = pl.DataFrame(data)
test.write_parquet('test.parquet')
time.sleep(2)
test = test.select(pl.col("col1"))
lock = FileLock('test.parquet')
with lock:
    test.write_parquet('test.parquet')

Log output

Issue description

Due to the Lock Polars returns a ComputeError and deletes the file, even if it was completely valid.

Expected behavior

The file should not be deleted if polars cannot touch it

[orlp]

I can't reproduce on MacOS. You didn't follow the issue template and showed us the output of pl.show_versions().

I have added the output of pl.show_versions()
