However, just to be sure, try excluding the calibre install directory in the
Windows Defender Security Settings->Virus & threat protection settings panel - should only takes a moment to check.

For diagnostic purposes only, try
- running calibre in Windows Safe Mode;
- running calibre as Administrator;
- using the CALIBRE_OVERRIDE_DATABASE_PATH Environment Variable to relocate the library database to somewhere like C:\calibre
