There surely must be some other detail(s) some of you could find for me to not expect the bitcoin core software to work and give up on the question I asked?

We already mention almost all option. Parameter -reindex and -reindex-chainstate are the only option Bitcoin Core provide when your blockchain file is corrupted. Besides, I/O error and missing files usually related with your hardware.

Normally i DO NOT recommend this, but you could try remove all files inside "index" folder, then run Bitcoin Core with -reindex parameter. If your NAS has slow I/O speed, it could take few days. And if you still see same LevelDB error message, you definitely you should check your hardware.

ETFbitcoin -- thanks for the suggestion. I tried moving all the files inside the "index" folder then running Bitcoin Core with -reindex but it immediately abended with the same error as before. Here is the log created by my attempt to follow your suggestion:
