[Windows] Codex 26.814.5167.0 fails to launch with "untrusted mount point" when Alibaba Cloud Drive is running

Bug report

Environment

• Codex Desktop: 26.814.5167.0 (Microsoft Store / MSIX)
• OS: Windows 11 24H2
• Architecture: x64

Problem

Immediately after updating Codex to 26.814.5167.0, the app fails to start when Alibaba Cloud Drive (阿里云盘) is running.

Windows shows:

C:\Program Files\WindowsApps\OpenAI.Codex_26.814.5167.0_x64__2p2nqsd0c76g0\...\ChatGPT.exe 无法遍历该路径，因为它包含不受信任的装入点。

The corresponding Windows error appears to be STATUS_REDIRECTION_NOT_TRUSTED (0xC00004BE).

What was verified

• Get-AppxPackage -Name OpenAI.Codex reports Status : Ok.
• The installed package is OpenAI.Codex_26.814.5167.0_x64__2p2nqsd0c76g0.
• The package root under C:\Program Files\WindowsApps can be accessed and enumerated normally.
• The package root entries do not show ReparsePoint/Junction in LinkType.
• C:\Users\<user>\Documents\Codex is a normal directory, not a Junction/Symlink.

Reproduction

1. Install/update Codex to 26.814.5167.0 from the Microsoft Store.
2. Start Alibaba Cloud Drive.
3. Launch Codex.
4. Codex fails to start with the "untrusted mount point" / unable to traverse path error.
5. Exit Alibaba Cloud Drive completely.
6. Launch Codex again.
7. Codex starts successfully.

Expected behavior

Codex should start normally regardless of whether Alibaba Cloud Drive is running.

Actual behavior

Codex fails to launch only while Alibaba Cloud Drive is running. Exiting Alibaba Cloud Drive immediately restores the ability to start Codex.

Additional context

This strongly suggests an interaction between the new Codex MSIX package/startup path handling and Alibaba Cloud Drive's filesystem integration, virtual filesystem, sync driver, or mount/redirection mechanism. The issue did not occur before updating Codex and is reproducible by keeping Alibaba Cloud Drive running.

Please investigate whether the new Windows/MSIX Codex startup path or filesystem trust checks are incompatible with Alibaba Cloud Drive's filesystem integration, and whether the interaction can be mitigated in Codex.
