Same thing happens to me. If I'm trying to send a full size jpeg, it disconnects. I am on Android 11, OnePlus 7 Pro, shooting on an XT3. I only shoot RAW, then convert to JPEG after on the camera so I can send to my phone and edit. This stopped working at some point, only way I can successfully transfer photos is if I turn the "resize" back on which heavily compresses the image. This workflow used to work on the same phone. Not sure what happened but I am experiencing the same as you.
