Sony ARW images and MP4 AVC1 videos don't upload

I just installed Immich so I'm using 1.68.0. I was excited to read that 1.63.0 added Sony ARW support. But now I'm trying to drag an ARW photo, or MP4 video encoded with AVC1, from my Sony A7iii camera and it's not doing anything. I can, however, upload a random JPEG image. After dropping the Sony files, the drop indicator goes away but the upload process never happens.
