Created attachment 470906 [details] Console logs collected with verbose WebRTC logging enabled We are not able to provide a minimal repro, but what you might try to repro this is: 1. Set up Chrome Remote Desktop on a remote device per instructions in https://remotedesktop.google.com/ 2. Go to https://remotedesktop.google.com/ on an iPhone 15 Pro or Pro Max 3. Connect to the remote device set up in step #1 4. Tap the triple-dot button on the top right corner 5. Change `Video codec` from `VP8` to `AV1` 6. Close the menu. Try to operate on the remote device and observe Expected: Remote desktop is not frozen. Actual: Remote desktop appears to be frozen. Based on the `Stats for nerds` panel, the number of frames decoded is 0. You need to change the video codec back to VP8 to unfreeze it. WebRTC logs are attached below.
