I'm trying to upload cover art for this release

https://musicbrainz.org/release/7014d947-10e0-4ed9-8317-b1fb294bc156

but it always results in '⚠ Error uploading image'. I've downloaded the cover from multiple sources, refreshed and cleared cache, tried in another browser, etc. I'm going to try on another computer tomorrow, but I haven't had this issue with other releases.

When I do try to upload for this release, it jumps from the small amount of progress to almost full in each instance, when I usually notice it doing so in pieces.
