Application crash after loading a new scene with Airpods connected

[AldenBraverman]

I am having an issue with a crashing iOS application after loading a new scene with Airpods connected. Upon loading a new scene, without connecting Airpods, the application runs properly. However, as soon as Airpods are connected the application crashes. I am using Unity 2020.3.0f1, running iOS 14.6 on an iPhone 12 Pro. Below is the log collected from Xcode with the application crashing:

@AldenBraverman do you have a simple project which shows this issue that I could test out?
