I’m facing problems in iOS 15.0+ with WKWebView plugin and assertion listed below,

[assertion] Error acquiring assertion: <Error Domain=RBSAssertionErrorDomain Code=2 “Specified target process does not exist” UserInfo={NSLocalizedFailureReason=Specified target process does not exist}>

[ProcessSuspension] 0x116004cc0 - ProcessAssertion: Failed to acquire RBS assertion ‘ConnectionTerminationWatchdog’ for process with PID=16547, error: Error Domain=RBSAssertionErrorDomain Code=2 “Specified target process does not exist” UserInfo={NSLocalizedFailureReason=Specified target process does not exist}

[assertion] Error acquiring assertion: <Error Domain=RBSAssertionErrorDomain Code=2 “Specified target process does not exist” UserInfo={NSLocalizedFailureReason=Specified target process does not exist}>
