/**
 * Loads a task from the disk.

 * Do not hold the window manager lock when calling this method, as we directly read data from
 * disk here, which might be slow.
 *
 * @param taskId The id of the task to load.
 * @param userId The id of the user the task belonged to.
 * @param reducedResolution Whether to load a reduced resolution version of the snapshot.
 * @return The loaded {@link TaskSnapshot} or {@code null} if it couldn't be loaded.
