Hello, I've just received an email with two attachments: a 28kB PNG and a 18MB ZIP. I can double-click and show the image normally, but when I do the same on the ZIP, I get a "is not an archive" error. If I try to save the attachments on the desktop, the PNG gets saved normally, while the ZIP shows up as a 27-bytes file. I'm using Thunderbird 102.9.0 (64-bit) on Linux. If it's relevant, under "Synchronization & storage -> Disk space" I have "Syncronize all messages locally regardless of age". Thanks for your help!
