iOS 14.5 Sometimes crash

[juraam]

Hello,
I use your library for video export using CoreAnimation Tool. But on the last iOS update(14.5) I noticed that exporter finished export with error: Error Domain=AVFoundationErrorDomain Code=-11819 "Cannot Complete Action" UserInfo={NSLocalizedDescription=Cannot Complete Action, NSLocalizedRecoverySuggestion=Try again later.} .
I have found on apple forums: https://developer.apple.com/forums/thread/679862 it sounds similar.
Do you know how can I fix that error ?
Thank you
