Unable to view FCP videos on Apple TV 4K when exported from FCP using the export Apple Device 4K

After I upgraded to FCP 10.5.4, when I attempt to export Final Cut Pro videos and attempt to stream to an Apple TV 4K device, i get the error, "The video is in a format that can't be streamed to this device." If I look at the compatibility for Apple Device 4k..., it only appears to be incompatible with any Apple devices. This feels like a codec problem, but I can't see a way to fix it. This did not happen with previous FCP versions.

If I drop the resolution down to 1080 and export, it will work. I'm able to stream other 4K videos, just not ones created on Final Cut Pro using the Apple Device 4k... default option.

How do I get compatibility on Apple Devices, including Apple TV 4K, when exporting from FCP at 3840 x 2160?
