--- Comment #1 from faalagorn@gmail.com --- I've have the same exact issue while trying to upload a screenshot for Escape
From Tarkov (I'm a super maintainer). I also got the same exact "Unable to move
screenshot from '' to '/home/winehq/opt/appdb/data/screenshots/originals/51218" 51218 being a latest iterating number at the end - suggesting it's probably some kind of request number.
Initially I tried uploading it under 2.6 version of wine with the description of "Playing as Scav", though even after shortening the description to "Scav" without any spaces and choosing a different (2.7) Wine version, the error persisted. I also tried moving the image to my home folder locally and renaming it to something shorter, removing spaces in the process, but it did not help either.
Initially I thought the error may be due to a too big size (my screenshot is 4 MiB), but I see OP screenshot is smaller size at 2.03 MiB. I didn't find any guidelines about the maximum file size though, and the error message doesn't suggest anything either. I also suspected PNG being an issue, but again, I didn't found any guidelines on this matter - at worst, the error message should reflect it, though I believe PNG support being a standard nowadays.
I'm also attaching my screenshot as an attachment.
