--- Comment #2 from Bruno Jesus 00cpxxx@gmail.com --- The path /home/winehq/opt/appdb/data/screenshots/originals/50324 looks like the address of the appdb upload folder inside the server. The number is the image number, like in the screenshot URLs from appd, eg https://appdb.winehq.org/appimage.php?iId=20868
It could be a file size limitation.
