Asset validation failed due to unsupported Xcode or SDK type

Hi! First timer here. I am having trouble uploading to App Store Connect. I uploaded an earlier version a ~week ago, but am now getting an error saying that the asset validation failed because of an unsupported version of Xcode or SDK. Not sure how to proceed or what specifically is causing the error. I speculated it was the Spotify iOS SDK, but have every time I got into Project > Package Dependencies > "—" button for the Spotify SDK, Xcode crashes.

System: MacOS Sequoia Beta 2 Xcode: 16 Beta 3

(All fully up to date)
