Well, first you should probably be specifying -a 0, not -a 3 since you seem to trying to load wordlists, not a mask. Second, it seems like your hash.txt file is empty, since hashcat is unable to find any hashes in it. Please make sure that the hashes are present in the file, and are formatted correctly, 1 per line.
