Imigration assistant forced me to restore my latest time machine backup which corrupted my clean installed high sierra with all fonts becomming question marks with boxes around them. My hope is that my earlier time machine backups arent corrupted like my latest one. If thats the case, how do i override apples migration assistant from restoring the latest time machine backup? Is there a way to select and restore a time machine backup earlier than the lates one?

Below are pictures of my corrupt os after time machine backup.
