Teams Optimization Crashes Windows App on macOS (AVD)
Summary: When using the Windows App for macOS (from App Store) to connect to Azure Virtual Desktop, enabling Teams Media Optimization causes the app to crash when joining or receiving a Teams call. Started about 3 weeks ago. Environment: App: Windows App for macOS App Version: 11.1.4 (Build 2557) - (I have also experienced this on 11.0.4 on another MBP M1 Max laptop I have.) macOS: 15.3.2 (Seqouia) Mac: MacBookPro18,1 (Apple Silicon) AVD Host: Windows 11, Teams (new client), Media Optimization enabled Crash Log: *** -[__NSArrayM objectAtIndexedSubscript:]: index 0 beyond bounds for empty array Type: NSRangeException Signal: SIGABRT Stack trace points to redirection plugin initialization Happens onlywhen Teams optimization is enabled Console Errors (macOS): BASIX_DCT(WARN): Not firing OnClosed on an object already closed. Stateful object was destructed while in state Opened(19) VirtualChannelEntryEx failed MSCOMVC plugin failed to load Repro Steps: Use a Mac with Continuity Camera or External webcam (in my case, Logitech Brio) Launch Windows App for macOS Connect to AVD session with Teams optimization enabled Initiate or receive a Teams call App crashes with SIGABRT Workarounds: ❌ Disabling UDP and device redirection has no effect. ⚠️ Disabling Teams Optimization prevents the crash. Far from ideal because now my audio and video quality are degraded when using teams on AVD (and my organization requires "camera on" for meetings 🔍 Relevant Log Snippets from macOS Console & Windows App (Teams Optimization Crash) ✅ Camera Enumeration Warning system_profiler SPCameraDataType Model ID: UVC Camera VendorID_1086 ProductID_39501 Model ID: FaceTime HD Camera Model ID: iPhone14,2 Continuity Camera detected alongside External Webcam and internal FaceTime camera. ⚠️ macOS Console Log BASIX_DCT(WARN): Not firing OnClosed on an object 0x11798e400 which is already closed. Happens right before crash — indicates plugin channel was torn down unexpectedly. 💥 Objective-C Crash Report exceptionReason : { "name":"NSRangeException", "type":"objc-exception", "composed_message":"*** -[__NSArrayM objectAtIndexedSubscript:]: index 0 beyond bounds for empty array", "class":"NSException" } Plugin crashes when accessing a camera/mic array that was unexpectedly empty. 🔗 Windows App RDC Log (DynVC Activity + Plugin Crash) DynVC.cpp(686): InvokeCallback() ...Sending up 6650 bytes VirtualChannelEntryEx failed Failed to load MSCOMVC plugin, maybe not enabled Stateful object 0x1218b4018 was destructed while in state Opened(19) AV redirection plugin begins initializing, then fails midstream. Memory cleanup errors confirm improper plugin teardown. 📉 Diagnostic Upload Failures FlushTracesInternal() is called before BeginUpload(). we don't have a claims token yet and thus can't generate sass token. cancelling flush Shows why Microsoft likely isn’t receiving telemetry unless the user manually reports. These logs help pinpoint the crash to Teams AV plugin failure in the Windows App on macOS, triggered by improper handling of macOS camera/mic devices (especially Continuity Camera or UVC) when Teams Optimization is enabled.henropotterMar 29, 2025Copper Contributor128Views0likes0CommentsUser keeps getting the pop up to log in Outlook when more than 1 email account is added
Hello, We're having an issues where our users keep having to log in to Outlook whenever they connect to the server when they have more than 1 email account added to Outlook. Users with only 1 mailaccount don't have this problem. We use fslogix profiles for our users. Any idea what could be the cause and how we can fix this? Kind regards,Vincent_BMar 24, 2025Copper Contributor18Views0likes0CommentsUnable to logon using Dell WYSE terminals
Hi all, I'm having an issue logging into AVD from Dell WYSE terminals. I have created a dynamic host group and added a service principal for them per guidance from Microsoft, and that has fixed an issue where the permission granting pop up was not displaying. After that, logon works fine with the web client but it will not complete sign-on with the Dell WYSE client. I have found the following errors in Azure AD but at a loss how to resolve as I have already added a service principal to the dynamic groups for hosts and unable to add a service principal for Windows Virtual Desktop AME.SamKMar 19, 2025Copper Contributor26Views0likes0Comments[On demand] Azure Virtual Desktop hostpool management at scale

Was redirected here, original post: https://techcommunity.microsoft.com/t5/azure-virtual-desktop-feedback/ipad-rd-client-keyboard-in-app-shortcuts-problems/idi-p/4182429 Hello, So here is the problem I face: My keyboard is working perfectly fine whenever I use it regurlarly, however, there seem to have problem when using shortcuts in apps. Like, most of the time, I must to Ctrl + w instead of Ctrl + Z for having the Ctrl + Z working. I Have a french keyboard, AZERTY, and it looks like the shortcuts are swapped? There are problem with those in different apps in any case; Seenda keyboard. Also, problem when using Blender, I did dug up an old post (https://techcommunity.microsoft.com/t5/azure-virtual-desktop-feedback/blender-does-not-recognize-keyboard-input-with-rdclient-for-ipad/idc-p/4182412#M3302) since I have the same problem, but will put it there too, but it seems that alphabetical and numerical inputs are not sent at all while using this program. (Also, when moving things around in the viewport with middle mouse button, the stream freeze while moving and can't see how it update live, which is bothering (EDIT: Other problem that will be adressed in another post).) Seems to be 3D apps in general? 3D Coat doesn't register shortcut either (tried enter, and Alphabetical).
