We cannot submit a release to streaming services, even if only one file has an issue (and you don't mind it being withheld from release). This is because we cannot delete/edit the tracks on a release once it is uploaded, and the error'd track is still associated with the release.
You'll need to abort the upload and re-upload a corrected version of the album, ensuring that your artwork and audio files meet all requirements.
Please see here for some specific information about uploading via iOS:
