Using AVAsynchronousKeyValueLoading.load() on an AVAssetTrack gives an error

I'm seeing this error while attempting to compile my VisionOS app under Xcode 26. My existing code looks like:

let (naturalSize, formatDescriptions, mediaCharacteristics) = try? await videoTrack.load(.naturalSize, .formatDescriptions, .mediaCharacteristics)

This is now giving a compiler error: Type of expression is ambiguous without a type annotation

I don't see that anything that was changed or deprecated in the latest version. Also loading the properties individually seems to work fine i.e.:

let naturalSize = try? await videoTrack.load(.naturalSize)
let formatDescriptions = try? await videoTrack.load(.formatDescriptions)
let mediaCharacteristics = try? await videoTrack.load(.mediaCharacteristics)
