Description
Bug report
Bug description:
import os
os.path.exists("C:/users/<username>/appdata")
Expected result: true.
Actual result: false.
This appears to be a regression introduced with gh-102765 when python moved towards using the new 'GetFileInformationByName' API function on Windows. This seems to have issues when the file/folder is on a profile managed by FSLogix.
The issue exists from Python 3.12.0 through to the latest public release (3.13.3).
Windows version: Windows Version 11 24H2 Multi-Session 26100.3775
FSLogix version: 3.25.202.4223
CPython versions tested on:
3.13
Operating systems tested on:
Windows

Research direction
Start by reproducing the os.path.exists and os.path.stat behavior on Windows with an FSLogix Redirected Container, then inspect the change from gh-102765 and its use of GetFileInformationByName. Done means the reported path operations return the expected result on Python 3.12 and later without regressing other Windows filesystem behavior.
