Hello, I'm having a problem with my Iphone 12:

iOS version: 17.5.1
Model name: Iphone 12

When I call someone it's impossible to communicate, it seems that the microphone is deactivated or that it doesn't respond. I was able to extract the ips file from the "data": stacks+audiomxd-.... Here's an extract:

{"bug_type":"288","timestamp":"2024-06-16 22:44:25.00 +0200","os_version":"iPhone OS 17.5.1 (21F90)","roots_installed":0,"incident_id":"7B8604DF-3863-4760-806C-591A90A7A7A4"}

As you can see, one line states : "reason" : "XPC message timeout in -[AVAudioSessionRemoteXPCClient getProperty:propertyName:MXProperty:reply:], probably deadlocked. Writing a stackshot and terminating.",

Deadlock occurs when two or more processes are waiting for resources held by the others, creating a situation where none of the processes can progress. In this case, it seems that the process has tried to recover an audio property, but has remained blocked indefinitely.

What reinforces my doubts is that at the end of the .ips is a line that seems to give some informations as to where the problem is : "notes" : ["Requested by audiomxd","_dyld_process_info_create(623) for resampling UUIDs failed with 1","_dyld_process_info_create(2535) for resampling UUIDs failed with 1","_dyld_process_info_create(3181) for resampling UUIDs failed with 1","_dyld_process_info_create(3183) for resampling UUIDs failed with 1","_dyld_process_info_create(3503) for resampling UUIDs failed with 1","resampled 409 of 1813 threads with truncated backtraces from 0 pids: ","resampled 625 of 37 images missing from 175 pids: 75,93,98,178,190,210,...,3627"],

Here's what my research yielded. Could you please help me? All calls are useless because the microphone no longer works.
