Version: 1.3883.0 (Windows MSIX)
OS: Windows 11
Description:
After updating to 1.3883.0, clicking "Trust Workspace" shows error
"Trust settings couldn't be saved" and app is completely blocked.
This worked fine before the update.
Root cause suspected:
CodexSandboxUsers group has only RX permission on .claude.json —
cannot write trust settings after update reset file permissions.
hasTrustDialogAccepted is already true in .claude.json but app still blocks.
Steps to reproduce:
- Update Claude Desktop to 1.3883.0 on Windows
- Open any workspace (previously trusted or new)
- Click "Trust Workspace"
- See error: "Trust settings couldn't be saved"
- App is completely blocked, cannot proceed
Expected: Trust is saved, app proceeds normally
Actual: App blocked completely
