--- It also prints the total time taken for the project sync operation.

--- It first checks if the `config.Haerald` table exists, and if not, it creates it and populates it with settings from the bundle.
--- It then sets the `config.Haerald.platform` to the current platform name.
--- Next, it calls `SetupRemoteDebugger()` to configure the remote debugger with the appropriate IP address, remote root, and project folder.
--- Finally, it calls `StartDebugger()` to start the debugger, and then calls `ProjectSync()` to initiate the project sync operation.
--- If the project sync operation fails to start, it sets `Updating` to `false`.
