Error msg "Warning - failed to read metadata"

Calibre 7.1 has repeatedly given me the following error message when I attempt to load four .AZW files I downloaded from Amazon.com to my Kindle. Thanks in advance for any assistance.

WARNING: Failed to read metadata: Failed to read metadata from the following:

Those are operating system supplied errors. Is your disc full, by any chance? Or is it in the process of failing?

That's a disk error indicating calibre could read from disk. I suggest running a disk scan and or disabling your antivirus program (some of the more asinine ones tend to prevent calibre from reading from its files).
