LogAudioMixerAudioUnit: Warning: Error querying Sample Rate: 2003332927

When I tried to launch the project on my iPhone, I got such an error. I have no clues about this.

LogAudioMixerAudioUnit: Warning: Error querying Sample Rate: 2003332927

Could someone help me? Thank you!

Same with me trying to launch on iPad.

I get the same warning message.
I am running Unreal Editor on a M1 MacBookPro.
