Remove the EXIF metadata of some TIFF files in .NET

When we remove the EXIF metadata of some TIFF files, we cannot use the removed files to initialize the Metadata instance, it will throw an exception: GroupDocs.Metadata.Exceptions.GroupDocsMetadataException: 'Image loading failed.'
The version of GroupDoc we are using is 22.9.0.0.

using (Metadata metadata = new Metadata(fileInput))
{
IExif root = metadata.GetRootPackage() as IExif;
if (root != null && root.ExifPackage != null)
{
root.ExifPackage.Artist = “artist”;
ushort tagId = 40095;
if (root.ExifPackage[(TiffTagID)tagId] != null)
root.ExifPackage.Remove((TiffTagID)tagId);
metadata.Save(fileOutput);
}
}
using (Metadata metadata = new Metadata(fileOutput)) //
{
IExif root = metadata.GetRootPackage() as IExif;
if (root != null && root.ExifPackage != null)
{
Console.WriteLine(root.ExifPackage.Artist);
}
}
