Hi @SouSingh , thanks for your work.

From the snapshot, it looks like your python release is from python.org, is it? And what's the system, Windown10 or 11?

Hi @yantaozhao I using Python 3.10.2 and the Device is Windows 11

it seems that the bug exists on Windows10

I can't reproduce the issue on Windows 11 with con.json, but with the filename con I've got your problem. However, con is a reserved name in Windows, even if it have any prefixes. The MS's document said:

Do not use the following reserved names for the name of a file:

CON, PRN, AUX, NUL, COM0, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT0, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9. Also avoid these names followed immediately by an extension; for example, NUL.txt and NUL.tar.gz are both equivalent to NUL. For more information, see Namespaces.

I doubt this is not a Python related issue but a Windows issue, and in any case, I think you should not use the reserved file name on Windows.
