The requested operation requires elevation. (os error 740)
What steps can reproduce the bug?
Notes:
- Closing/reopening Codex did not fix it.
- Running as administrator did not fix it.
- Repair failed in Windows Settings.
- Reset did not fix it.
- Uninstall/reinstall did not fix it.
- Main command runner sandbox setup from Program Files\WindowsApps appears to succeed, but browser/node helper uses the cached helper under AppData\Local and fails.
What is the expected behavior?
