When trying to save a 15-minute movie from iMovie in order to upload it in the YouTube app, I frequently get the message "Storage Full: There is not enough space left on this device. You cannot share until you free some space."
This despite the fact that Settings shows "28.8 GB of 64 GB Used" and that iMovie is using only 1.29 GB of that. (It also shows that iMovie was "Last Used: 12/12/18" which is clearly false; is that a clue that the storage graph is inaccurate?)
How can I get iMovie to use this 35G available space for its export?
iPad Air 2, iPadOS 14.2, iMovie 2.3.2 (5087)

It's a "known issue" that has been around for years according to various threads of people encountering the same problem. Apple has no intention of fixing it, otherwise they would have by now. The only workaround I've found to be consistent is to delete all other projects, edit a video, leave it for like a month, then try to export it.
