iOS 26.2.1 Crash: -[UIWindowScene layer]: unrecognized selector after video call ends (ZoomVideoSDK 2.3.0)

lasmarthomedev · March 10, 2026, 5:52am

Issue Description

I’m experiencing a reproducible crash on iOS when using ZoomVideoSDK 2.3.0 (build 27010). The crash occurs after a video call ends during the audio device cleanup phase.

Crash Details

Exception:

NSInvalidArgumentException: -[UIWindowScene layer]: unrecognized selector sent to instance 0x139927200

Exception Type: EXC_CRASH (SIGABRT)

Trigger: The crash is triggered by a timer callback inside ZoomVideoSDK during the session cleanup process.

Environment

Device: iPhone 16 Pro (iPhone17,2)
iOS Version: 26.2.1 (23C71)
Architecture: arm64e
ZoomVideoSDK Version: 2.3.0 (27010)
MobileRTC Version: 6.2.5 (18740)
Build: TestFlight Beta
App Runtime: ~57 minutes before crash
Battery: 45%
Available Disk: 11.7 GB / 255 GB

Crash Scenario

Trigger Sequence (from logs):

2026-03-09 18:05:28.459 User Leave，Current remote users num: 0

2026-03-09 18:05:28.502 AudioDeviceIOS::SetMuteOutputAudioUnit unmute output

2026-03-09 18:05:28.504 [IOS].DestoryAudioUnit g_audioUinits.count = 1

2026-03-09 18:05:28.624 [IOS].DestoryAudioUnit dispose all audioUinits

2026-03-09 18:05:28.662 *** Crash: -[UIWindowScene layer]: unrecognized selector

The crash happens immediately after:

Remote user leaves (remote user count → 0)
Audio device cleanup starts
ZoomVideoSDK timer callback fires

Related Code in My Implementation

**Delegate Implementation (CanvasViewController.m)

(void)onUserLeave:(ZoomVideoSDKUserHelper *)helper users:(NSArray<ZoomVideoSDKUser *> *)userArray {

for (int i = 0; i < userArray.count; i++) {

  ZoomVideoSDKUser \*user = userArray\[i\];

  // Update UI

  \[self.bottomView removeThumberViewItemWithUser:user\];

  \[self.avatarArr removeObject:user\];

  

  if (self.fullScreenCanvas.user == user) {

      \[self pinMyself\];

  }

  // Handle PiP for photo sharing

  if (self.isUsingNewPhotoShareFlow && self.photoShareBrowserView && \[user isEqual:self.currentPiPUser\]) {

      NSArray<ZoomVideoSDKUser \*> \*remainingRemoteUsers = \[\[\[ZoomVideoSDK shareInstance\] getSession\] getRemoteUsers\];

      

      if (remainingRemoteUsers.count > 0) {

          ZoomVideoSDKUser \*nextUser = remainingRemoteUsers.firstObject;

          \[self updatePiPForUser:nextUser\];

      } else {

          \[self hidePiPForPhotoShare\];

      }

  }

}

[self updateTitleIsJoined:YES];

NSArray *remoteUsers = [[[ZoomVideoSDK shareInstance] getSession] getRemoteUsers];

// Auto-leave if only one user remains

if (remoteUsers.count == 1) {

  dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2.0 \* NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

      \[\[ZoomVideoSDK shareInstance\] leaveSession:YES\];

  });

}
