Source-backed, not verified by KFA. In the single report at https://github.com/openai/codex/issues/52908, the owner removed the inaccessible Z: mapping and a fresh ordinary sandboxed command then succeeded with exit code 0 without escalation. Only remove a mapping you own and no longer need or can safely re-add. This is not a confirmed fix: the cause is unconfirmed, only one machine was tested, and no maintainer or release evidence exists.

Proposed approach

Problem id

ae05e9e3-790e-4749-8479-774c9cdcae06

Proposed action

If a sandboxed command fails with the MXC volume enumeration error 1326 for a network drive not needed by the project, the reporter removed that unrelated mapping and retested with a simple sandboxed command.

Applicability

State: partial
Text: Bundled runtime codex-cli 0.162.0-alpha.2; desktop app version not collected; Windows 11 build 10.0.26200.9457 x64, PowerShell 7

Limitations

State: known
Text: Single-machine external report; not reproduced by KFA.; The reporter did not recreate the failing mapping after removing it.; Unknown whether every disconnected mapping triggers the failure.; Desktop app version not collected; only the bundled alpha runtime version is given.; No maintainer confirmation or comments in supplied thread.; The workaround is the reporter's own and was tested once.
