I'm having this issue inside of visionOS on simulator and real device. It only shows up for some people. Exact same setup and code will run fine for other users.

Hi everyone. Just make sure to update XCode and you'll be good to go. I solved this by updating to the latest XCode version.

Any update?

There is a bug in the player where only MV-HEVC HDR10 files that are marked with the ProjectionType of "Fisheye" and have the REQ-VIDEO-LAYOUT of "CH-STEREO/PROJ-FISH" in the master playlist will playback. You need to re-encode your MV-HEVC video with the Fisheye projection type and then set the layout to PROJ-FISH. You can go to here for more information: https://spatialgen.com/blog/hdr10-mvhevc-hls
