I reported -11819 failure via FB9166298. It is estimated that -11819 occurs more frequently when AVVideoCompositionCoreAnimationTool is used and the resolution of the video to be exported is higher(like 4K). Because, if I do not use AVVideoCompositionCoreAnimationTool or set it to a resolution lower than 4K, the case that caused the -11819 error was solved.
