WebView video freeze

Hi, I'm try to use WebView Plugin for WebGL to play stream video, work fine in PC and Android, but in iOS the video is freeze, just like pause, try to call Reload() or Resume() doesn't work.

I didn't see any useful info in Xcode Device Monitor but these message:
Error acquiring assertion: <Error Domain=RBSServiceErrorDomain Code=1 "(originator doesn't have entitlement com.apple.runningboard.assertions.webkit AND originator doesn't have entitlement com.apple.multitasking.systemappassertions)" UserInfo={NSLocalizedFailureReason=(originator doesn't have entitlement com.apple.runningboard.assertions.webkit AND originator doesn't have entitlement com.apple.multitasking.systemappassertions)}>
I don't know this message mean, could it is possible about this problem?

And in my code I set the "enableWKWebView:true" when call Init().

Unity : 2022.1.12f1
Using template : unity-webview-2020
iOS : 15.6.1

Start with the WebView Plugin initialization using enableWKWebView:true and reproduce the freeze on iOS 15.6.1 with Unity 2022.1.12f1, checking the Xcode Device Monitor output. Compare the behavior of Reload() and Resume(); done means the stream video plays normally on iOS rather than remaining paused, with the entitlement message understood or ruled out.
