Recover without exposing your project.

Google sign-in does not return

• Leave the Meloft sign-in window open
• Finish in the system browser, not an embedded browser
• If the flow expired or was cancelled, return to Meloft and start a new sign-in
• Do not copy callback URLs or authorization codes into support messages

A Handoff link does not open Meloft

• Confirm Meloft is installed
• Use the complete canonical meloft.app/handoff link
• Choose Open Meloft on the bridge page
• If the code expired or was revoked, ask the sender to create a new Handoff

Project Doctor cannot read a project

• Confirm the source still exists and is readable
• If a ZIP contains several FLPs, select the intended candidate
• Retry after the project has finished saving
• Keep the original unchanged and review the structured error

A sample is missing

• Review whether the reference is external to the project folder
• Locate the asset yourself before preparing a package
• Do not treat a lower risk label as proof that the sample will travel

A plugin is Unknown

• Run Capability scan again
• Confirm the VST3 is installed in a standard or explicitly scanned root
• Unknown is intentionally conservative; it is not automatically Missing

An update fails

• Close active Meloft windows if the installer reports a file lock
• Open the Launcher again to retry
• Do not download an installer from an arbitrary R2 or third-party URL

Reset window state

Use the existing Settings window-state recovery control. This is separate from account, Project Library, and project data.
