I'm seeing something similar too:
VersOne.Epub.EpubPackageException: Incorrect EPUB manifest: item with ID = "cover" is missing.
VersOne.Epub.Utils.TaskExtensionMethods.ExecuteAndUnwrapAggregateException[T]

Yeah, this is the most common problem among the EPUB books. I'll add a workaround in the next release.

Implemented in version 3.3.3.

@daviddphillips, for the Incorrect EPUB manifest: item with ID = "cover" is missing error: these errors will be automatically ignored, if your application doesn't pass a custom EpubReaderOptions instance into a EpubReader method. Otherwise, you will need to set EpubReaderOptions.BookCoverReaderOptions.Epub2MetadataIgnoreMissingManifestItem to true.

@sattasundar, for the Incorrect EPUB spine: item with IdRef = "cover" is missing in the manifest error: it's not a common issue among the EPUB books, so it's not ignored by default. To ignore these errors you can use the following code:

EpubReaderOptions options = new(EpubReaderOptionsPreset.RELAXED);
options.SpineReaderOptions.IgnoreMissingManifestItems = true;
EpubBook book = EpubReader.ReadBook(filePath, options);
