Restoring Unsaved Session No Longer Works

[fuzenco]

Reproduction steps

1. Have a window open with code/text.
2. Close said window without saving first.

Current vs. Expected behavior

A few weeks ago, restoring windows worked. I happened to restart my computer (due to a macOS update) and my unsaved file was gone. I expected that upon starting Zed, that my file and its content would be restored. It wasn’t.

Testing, by creating new files, and restarting shows this is broken now. This is the error shown on restart:

My current prefs have Zed set to restore:
Restore Unsaved Buffers = Enabled
Restore On Startup = Last Session

Zed version and system specs

This issue appears to be a duplicate of:

• "Restore Unsaved Buffers" is not respected when closing the window on macOS #48468

If this is indeed a duplicate:
Please close this issue and subscribe to the linked issue for updates (select "Close as not planned" → "Duplicate")

If this is a different issue:
No action needed. A maintainer will review this shortly.

Why were these issues selected?

#48468: Both issues describe the exact same problem: unsaved content is lost when closing Zed windows on macOS using the red close button, but works correctly when using Cmd+Q. Both show the same error 'Failed to restore workspace: Workspace WorkspaceId(X) not found' and both have the same settings enabled (Restore Unsaved Buffers = Enabled, Restore On Startup = Last Session).

Shared root cause: Workspace restoration fails when closing Zed windows on macOS using the red close button instead of Cmd+Q, causing unsaved buffers to not be restored despite the 'Restore Unsaved Buffers' setting being enabled
