What I did (as example with Testflight version, but other user reported a similar behavior with the latest stable version):

1. created a 10 min video, ca 5.2 GB size
2. created a new vault one OneDrive and opened it.
3. started upload of the video (“preparing file“ circle is showing)
4. prevented the system to go to sleep (black screen) for about 12 minutes. Status did not change.
5. waited until iPhone display turned black
6. waked up iPhone
7. TestFlight window “something went wrong, do you want to give feedback to developers” showed up immediately
8. sent report (May 26).
