E2E MissingMetaDataException: Intermediate meta-data file missing

This started with me attempting to upload a few 50+ mb video files to a new E2E enabled folder. The first attempt allowed me to upload 2 video files then no more files would upload from the Android client. Then I created a new folder and enabled E2E and re-attempted. I still can’t upload to the E2E folder and now I have a file in there with a scrambled name which I can’t delete from the web or Android client. How do I delete a file I don’t have a token for and how do I investigate the original upload issue in more depth?

The error on the server is:
Error no app in context OCA\EndToEndEncryption\Exceptions\MissingMetaDataException: Intermediate meta-data file missing
