Issue:
apply_patch fails in the current Codex window on Windows before the patch is applied.

Platform:
Microsoft Windows NT 10.0.26200.0 x64

What I was trying to do:
I was testing whether apply_patch works in the current session with a minimal probe patch that only creates a temporary file.

Prompt:
“Check whether apply_patch can run successfully in the current window.”

ERROR:
execution error: Io(Custom { kind: Other, error: "windows sandbox: setup refresh failed with status exit code: 1" })

Minimal patch used:
* Begin Patch
* Add File: tmp/apply_patch_probe.txt
+apply_patch probe
*** End Patch

Actual result:
The patch did not run. No file was created and no business code was modified.

Full error message:
execution error: Io(Custom { kind: Other, error: "windows sandbox: setup refresh failed with status exit code: 1" })

Expected result:
apply_patch should apply the minimal patch successfully, or at least fail with a patch-validation error if the patch content is invalid. Instead, it fails during sandbox setup before patch execution starts.

Notes:

• This appears to be an environment/tooling issue rather than a patch syntax issue.
• The failure happens before any file write occurs.
• Other tools such as shell-based file reads/writes are working in the same session.

What steps can reproduce the bug?

Steps to reproduce:

1. Open a Codex session on Windows.
2. In the current workspace, run a minimal apply_patch action that should only create a temporary file.
3. Use the following minimal patch:

* Begin Patch
* Add File: tmp/apply_patch_probe.txt
+apply_patch probe
*** End Patch

1. Observe that apply_patch fails before the patch is applied.
2. Verify that the file tmp/apply_patch_probe.txt was not created.

Reproducible bug:
apply_patch fails in the current Windows session during sandbox setup, before patch execution begins.

Actual error:
execution error: Io(Custom { kind: Other, error: "windows sandbox: setup refresh failed with status exit code: 1" })

Expected behavior:
The patch should create tmp/apply_patch_probe.txt, or at minimum fail with a patch validation error if the patch syntax is invalid.

Minimal reproduction snippet:
* Begin Patch
* Add File: tmp/apply_patch_probe.txt
+apply_patch probe
*** End Patch

Verification command:
PowerShell:
if (Test-Path 'tmp\\apply_patch_probe.txt') { Write-Output 'EXISTS' } else { Write-Output 'MISSING' }

Observed verification result:
MISSING

What is the expected behavior?
