Failed to obtain workspace.

Error message

Failed to obtain workspace.

What it means

In project_panel undo's rename helper: the stored WeakEntity<Workspace> failed to upgrade, meaning the workspace was dropped while an undo operation was still running. The rename cannot be applied without the workspace.
