I can see you also sync AnkiDroid to your account, so you should be able to use that to restore anything that is missing on your computer.
- Enable airplane mode on your Android device, so it’s not connected to the internet.
- Open AnkiDroid – which won’t be able to auto-sync.
Settings > Sync > AnkiWeb account > Log Out.- Connect your device to the internet again.
- Log In to your AnkiWeb account again, and Sync.
That will force a rescan of your media, and the files will be restored on AnkiWeb. 19K is a lot of files, so that will take some time, and maybe a few tries. Once that’s done, you’ll be able to sync your computer and the files will be restored there.
